The Battle of Shaunsburg Part 4

 Dusk approached the battlefield near the little town of Shaunsville.  Less than two hours remained for the Confederate forces to score the breakthrough that could cut off the Union retreat and bag the entire Federal army.  The Army of the Potomac was holding on but barely. 

The battle rages on looking across from the Confederate left. 

The Union generals didn’t know it but the three objectives that were the target of the Confederate attack were on Birney’s hill in the center right of the Union line, on Artillery hill in the Union center left and along the fenced road on the Union left.  The Confederates had selected the objective on the far Union left but the objective was moved unknowingly during set up when the Union generals swapped it for the objective that had been on artillery hill as part of the rules of set up that allowed them to  switch two objectives of their choice  

7:20pm-9:00pm (Dusk)

The Union army held on for darkness.  On the Union far right the division of Hays continued to hold a strong position along a wall on the edge of a large wheat field.  After initially bristling at a Confederate brigade positioned across the wheat field, Hays pulled his division back and sent one of his brigades through the woods to his left and in the rear of Birney’s division near the center of the field.  Hays also pushed an artillery battery into a gap through some woods on the left of his front line, turned it and blasted advancing Confederates in flank as they tried to push up the hill in Birney’s sector.  

The aforementioned division of Birney finally had a second brigade  arrive and march out of the woods at the crest of the hill in the center right of the Union line.  Hobart Ward’s brigade of Birney’s division was in shambles and Ward was wounded. One regiment was run down when it attempted to flee through the cornfield.  Another regiment routed off the field and two others were battered.   Ward had paid a hefty price but his brigade had slowed the attack of  three Confederate brigades buying time for his two other late arriving brigades to march into position. The first of those brigades raced forward to a stone wall that stood at the foot of what was now being called Birney’s hill facing a farmstead situated between the wheat field  and corn field. 

The Confederates advance towards Birney’s hill 

The left flank of the Union line was the most threatened and had been under heavy pressure all day.  Artillery hill-now named for the three Union batteries anchoring the center left of the Union line had pounded the oncoming Confederates since the battle started.  Union cavalry had arrived in time to dismount and form a line at the base of the wooded face of the hill.  The Illinois and Indiana horsemen supported the guns but had taken a pounding and were being pressed heavily. 

The Confederates push against the Union cavalry and Artillery hill

On the Union far left the Iron Brigade held on. Three Confederate brigades with supporting artillery had failed to break them.  Now reinforcements from the two other brigades of Abner Doubleday’s division marched onto the field to support them.  One positioned itself along the road to the left of the Union cavalry and the other marched up the rear of Artillery hill. 

This was the Union situation with two hours remaining.

The Confederate plan was struggling to survive contact.  On the Confederate left in the wheat field the feint had been effective.  Kemper’s brigade held three Union brigades of Alexander Hays’s division in place even as six other Confederate brigades pounded two Union brigades elsewhere on the field. Now with one of those Union brigades moving off to shore up the Union middle Kemper started to advance. 

In the middle the Confederates had been held up by Ward’s stubborn brigade but had finally pushed it back and were advancing against Birney’s hill. Union reinforcements had all but ended any hope of taking the objective at the crest of Birney’s hill but it was paramount that the Confederates opposite the hill prevent Birney from sending help over to Artillery hill.

Artillery hill and the objective on that hill would be the primary target in the Confederate center. Three artillery batteries with no infantry support were all that held the top of the hill.  The arrival of a Confederate artillery battalion consisting of 24 guns in a field in the center of the Confederate line would bolster the attack on Artillery hill. 

The massed guns in the Confederate center would prove decisive

On the Confederate right Barksdale’s Mississippians had been wrecked in the attempt to push through.  Now it was to be the turn of McClaws’s other two brigades.  The Iron Brigade had received reinforcements.  The simple Confederate strategy was to push through them.  No finesse.   If the third objective was to be taken, it would likely have to be by the bayonet.  

This was the Confederate situation with less than two hours left. 

On the Union right the wheat field remained firmly in hand.  The Union sortie resulted in sporadic but largely ineffective firing.  It appeared with dusk approaching that the two sides would continue to pop shots off with no real effect but then suddenly James Kemper slipped the leash and turned a feint into a full charge.  Leading his men Kemper charged forward in an assault three regiments strong. The men crossed the first wheat field and slammed into an Ohio regiment who fired ineffectually and fell back.  The Confederates pounced on the Buckeye staters and captured them complete in the ensuing melee.  

Victory brought confusion to the Rebs.   Two Union regiments posted behind the split rail fence in the road loosed volleys striking down greybacks in droves.  This resulted in the beginnings of a panic.   Kemper was then shot down causing the brigade to route entirely.   A charge by another Union regiment against the remaining regiment of Kemper’s brigade ended in a repulse for the Yankees.  That ended the action on the Union right. 

The Louisianans facing Birney’s hill tried to dislodge the Union defenders from the stone wall at the base of the hill.  They were bloodily repulsed with the First  Louisiana taking 50% casualties.  The rest of the brigade reformed while supporting artillery pounded the wall.A second charge carried the wall but darkness ended any hope in this part of the field.  The first of the three objectives would not be taken by the Confederates.

An explosive sheet of flame erupts from the stone wall into the Louisianans 

Over on Artillery hill a race was being run.  Union reinforcements from Doubleday’s final deployed brigade was racing up the back side of the hill at the same time as Confederates pushed up the front. Withering fire from the Confederate battery of 24 guns deployed in the Confederate center knocked down Union cannoneers on the hill in droves. The fire was so accurate that not a horse was hit but one entire battery crew  was knocked out and the two others were reduced to a skeleton crew. 

Georgians and Virginians of Semmes’s brigade emerged from the woods at the top of the hill into a face full of double canister from the two remaining guns. One regiment routed but the unsupported guns were overrun. 

The hill is stormed. 

The freshly arrived Union brigade from the rear of Artillery hill sounded the charge and crashed into the Confederates who reformed from their disorganized state after taking the cannon. The Union wave overwhelmed the Confederates and after a decisive melee the Georgians and Virginians were driven off the hill.  

It was too little too late. Two more Confederate brigades swarmed the hill taking the second objective. 

On the far Union left the Iron Brigade’s desperate defense was coming to an end.  They had held off multiple attacks by multiple brigades for six hours.  Could they last one more?

In front of the cornfield on the extreme left flank, the last of McClaws’s brigades charged the far left regiment of the Iron brigade. A desperate volley halted the first Confederate regiment but the second smashed into the western farmhoys  causing them to route from the field.  Now in the cornfield, the Confederates reformed facing the flank of the entire Union line.  A regiment of one of Doubleday’s other brigades tried to blunt their attack but were driven back and captured in the ensuing melee. The Union left was crumbling. 

The final charge 

The last bastion of Union defense fired volley after volley into the approaching Confederates causing heavy casualties.  The 24 gun battalion of rebel artillery that had earlier caused so much damage now turned its guns on the Union left.  The bombardment lasted forty minutes.   The last remaining Yankee cavalry battalion sustained 50% casualties and routed. This was too much for the infantrymen to their left and they too routed.

The third objective was taken by the Confederates.

The Results

The Confederates had scored an incomplete victory.  By taking two of the three objectives they would cut off at least part of the Union army from escaping across the river.  The Iron Brigade lived up to their name and slowed the Confederate attack.  Ward’s brigade held off an even bigger attack with less help and saved Birney’s hill from being overrun.  Meanwhile, three Union brigades were feinted into immobility on the Union right when they could have seen better use on their left. 

The Confederates sustained approximately 7205 casualties of their more than 23000 engaged.  Two generals, Kemper and Walker were killed.   Semmes’s brigade of McClaws’s division sustained the highest number of Confederate casualties at 1050 of 1920 engaged (a 54% casualty rate) in taking Artillery hill.  On the positive side the Rebs captured 22 Union cannon and lost none.  

The Union sustained approximately 5870 casualties of the more than  22000 engaged.  Ward’s Brigade of Birney’s division sustained the highest number of casualties in the battle at 1140 of 2400. A 46% casualty rate.  In doing so they saved Birney’s hill and likely total defeat. 

Total casualties thus were approximately 13075 killed, wounded and captured out of approximately 46000 engaged.  

The war would go on…

The Battle of Shaunsburg Part 3

 In an attempt to capture three objectives and cut off the defending Union army’s retreat the Confederate attack ramped up in the next phase of the battle. The initial right flank attack gained strength and the Union hold on that part of the field was in for a challenge. 

Union troops hold the fence and the left flank of the defensive line. 

6:00pm-7:20pm

On the Union right flank Hays’ division was present in full on the field behind a fence in a wheat field.  They bristled menacingly and even advanced beyond the defensive line but participated little.  While the Union middle and left suffered under Confederate hammer blows the troops of the right sat firm holding off a single less than aggression Confederate brigade.  In nearly three and a half hours of fighting Hays’ division suffered only 540 casualties with 480 of these being from a single regiment caught marching to the center by a cavalry charge that hit them in column and swooped them up. 

In the Union center the situation was more grim. A single Union brigade held a stretch of nearly a mile of ground.  Parts of two Confederate divisions under John Bell Hood and D R Jones attacked and drove the brigade up the hill the Union troops were trying to protect.  This was the brigade of Hobart Ward of Birney’s division and it was near breaking.  The two other brigades of the division missed their six o’clock arrival time and were not in sight.  

An aggressive and steady push by two of D R Jones's brigades and a battery of horse artillery from Wade Hampton’s cavalry brigade was slowed but not stopped.  A brave sally forth by a lone Union regiment into the central cornfield was crushed by a Confederate charge but may have slowed the Rebel advance just enough as Carr’s Brigade finally arrived a full hour late. 

Carr arrives late but maybe not too late. 

On the Union left where the main Confederate blow had landed the Iron Brigade continued to stubbornly hold back parts of two Confederate Brigades under Barksdale and the Texas Brigade.   The timely arrival of Farnsworth’s cavalry and its repeating carbines as well as three artillery batteries lending support from atop a centrally located hill drove off the charge of the Texas brigade.    Barksdale was able to gain the far flank and hit the Union line in full enfilade with a charge that routed an Illinois cavalry battalion and rolled up the Union left flank. 

The Texas Brigade is held back 

Just as in the middle, the hard fighting Wisconsin and Indiana boys with support from the Cavalry received hammer blows but bought time.  Doubleday’s two other brigades arrived to try to support the crumbling flank.  

The Confederates too welcomed reinforcements.  Hood’s supporting artillery arrived and began pouring fire into a battalion of cavalry that was anchoring the right end of Doubleday’s left flank.   A point blank volley by a regiment in Evander Laws’ brigade sent another cavalry battalion running into the woods and up the hill in the Union center left.  If the Confederates gained that hill the Union center might collapse.  

Would the Union reinforcements win the race to drive off the Rebel attack?

Union troops march in behind the Union center 

In three hours of fighting 22420 Union soldiers suffered approximately 2670 casualties.  23580 Confederates suffered 3810 casualties.  Ward’s Union brigade in the center alone sustained 1140 casualties  while the entire division of Hays only suffered 540. Two Union brigades of roughly ten regiments supported by three battalions of artillery had held off parts of three Confederate divisions containing 30 regiments while three fresh Union brigades held off one Confederate brigade.  

Only a little over two hours of daylight remained.  Could the Union hold?

The Battle of Shaunsburg Part 2

 The battle of Shaunsburg began to develop with an aggressive right hook by the attacking Confederate army. Reinforcements were slow to arrive but the Brigades on the field began to come into range of each other.

Union batteries holding a hill in the Union center unleash on the approaching Confederates.

5:20pm-6:00pm

Barksdale’s Mississippi Brigade continued to advance with artillery support against three regiments of the Iron Brigade who marched out to meet them. The Black Hats charged the cannon that had been blasting them but were instead intercepted by four of Barksdale’s regiments led by Barksdale himself.  The Confederates crashed into the Western Brigade and knocked it back in disorder, routing one regiment and throwing two others into disorder. The Rebels were disordered as much by success as the Yankees were by defeat.  

Directly to the left of the charge the Texas Brigade tangled with two other regiments of the Iron Brigade and were ready to get stuck in when Union cavalry stampeded up the road behind the Union line, dismounted and fired repeaters to great effect. The charge of the Texas Brigade was broken up in confusion. The horse artillery and another cavalry regiment blasted the Mississippians who attempted to reform to face them.   

Shaken but not routed, the Iron Brigade fires into the Mississippians 

In the Confederate center left Hampton’s cavalry caught the Second New Hampshire marching in column along a road in front of them. They charged.  In the resulting melee the New Hampshire regiment is killed or captured to a man as sabres and pistols make short work of them.  The cavalry in turn sustained heavy losses from fire from both left and right as several Union regiments and a battery of guns moved to seal the breach.  One Cavalry Battalion fled and Hampton is wounded in the attack.   

A Union volley empties Confederate saddles. 

Meanwhile on the Union far right Hancock’s entire Corp is on the field in strength  

Look at that strength 

In two hours of fighting 22410 Union soldiers (half on the field) suffered approximately 780 casualties. In that same time 23580 Confederate soldiers (half on the field) suffered 1360 casualties.  The Union left and center are pressured but have not broken.  The battle continues.

The Battle of Shaunsburg Part 1

 Inspired by every American Civil War battle in which an army is forced (or chooses) to line up with a river to the rear and a limited route of escape should things go wrong, the Battle of Shaunsburg presents a portion of the Union army of approximately 22410 strong facing a Confederate Army of approximately 23580.   In this scenario using the Johnny Reb 3 rule set, the  Confederate Corp of General James Longstreet is attempting the crash through a portion of the Union army in order to gain the rear of the Union army and block its retreat. 

Looking across the field from the Union right 

The scenario begins at 4pm with parts of three Union Corps led by Generals George Meade (1st Corp) Winfield Scott Hancock (2nd Corp) and Dan Sickles (3rd Corp) holding a line across the length of about three and a half miles. Three Brigades and supporting artillery are on the field with three available roads from which to enter behind the Union lines.  Union reinforcements are scheduled to arrive at 6pm but several of the six Brigades in reserve are trying to arrive early. 

Three Confederate Brigades with supporting artillery enter opposite the Union line from six possible roads.  Those roads also provide the arrival points for seven additional Brigades that are scheduled to arrive at 5pm.  Both armies armies also have small cavalry detachments arriving in reserve. 

The Confederate goal is to take objectives behind the Union line.  These objectives represent punching holes and cutting off the avenue of retreat for the Union army.  Six objectives are on the board but only three secretly chosen by the Confederates are the true objectives and the Union side doesn’t know which ones. After all roads of entry are chosen and on board troops are set up, the Union Generals are allowed to swap two objectives possibly making Confederate troop dispositions less ideal. 

4:00pm to 5:20pm Union forces lined up left to right  with the Iron Brigade of Doubleday’s Division holding the far left near a small house and larger barn.  Hobart Ward’s Brigade of Birney’s Divison held a hill and farm in the center and  Caldwell’s Brigade of Hays’ Division aggressively pushed forward on the right near a large wheat field.

A pair of batteries on small hill in the Confederate center opened the attack to minimal effect.  The weight of the Confederate attack fell against the Iron Brigade as Barksdale’s Mississippi Brigade shook out skirmishers and advanced supported by a three batteries of mixed guns.  The Texas Brigade emerged from a wood shrouded Road to move on the center left and Garnett’s Virginians marching up the middle.

The opening fight erupted when Confederate batteries rained shot and shell into the Wisconsin and Michigan regiments who advanced from the protection of their fence to exchange fire. 

The Black Hats advance on the guns

Union batteries in the center chased off a Virginia regiment that disengaged and reformed.  Caldwell’s Brigade moved up to a stone wall in front of the wheat field but initially met no resistance.  

Confederate reinforcements arrived on the left in the form of Kemper’s Brigade and immediately exchanged cannon fire with Caldwell’s supporting battery but to little effect.  

The Union Cavalry of Farnsworth’s Brigade arrived on the Union left behind the Iron Brigade while Confederate Cavalry of Hampton’s Brigade galloped forth on the Confederate center left.  

Hampton arrives 

In an hour and twenty minutes four Confederate Brigades of infantry and a Brigade of Cavalry were on the field advancing on four Union Brigades of infantry and a Brigade of Cavalry.  Approximately 90 Union and 120 Confederate casualties served to decide little at this stage of the battle.  

The Union line was not yet tested but a dangerous gap was developing in the center and the on the Union left one Brigade was facing two.   What would the following hours bring?  Find out in part 2

The Battle of Novice Mountain Part 3

 The final hours of the Battle of Novice Mountain bring to its conclusion the bloody work started earlier in the day as Union forces try to hold the two flanking passes while taking the middle pass.  

5:40pm-7:00pm

McClaws’ Division on the far Confederate right has pierced the Union line at the wall and driven off the Zouaves of the 11th New York and the Irish Brigade but two Rhode Island regiments and the 3rd Maine drive them off routing two South Carolina regiments and driving beyond the wall their division originally held. They, in turn are struck  and driven back to the yard  but McClaws’ division is spent and can do no more.  The Union left has held.

New Englanders seal the breach and drive back the Confederates 

On the Confederate left near disaster strikes as down go two brigade commanders, and division commander Daniel Tyler is carried from the field.  It is fortunate that Corp commander Joseph Hooker is up and is able to stabilize the flank.  It may not be enough.  Several Union regiments and a battery of guns rout and Hood’s division has regrouped on the flank.  Massed artillery breaks a Confederate charge before it can be launched from behind a stone wall but farther left six regiments are sent forward against two Union regiments only to be thrown back in disorder.  If the charge had succeeded the flank would have broken.  The Union flank holds on the right.   

The Union line erupts in flame across the front. 

  In the center the more slowly developing Union push finally rolls across the widest pass.  The Confederate Division of DR Jones deals punishment from near a small farm house but is late in blocking the pass.  Jones decides it’s time to throw in a large brigade in an all out assault.   Like the assault on the Confederate left Jones has numerical superiority.  Six regiments charge the 3rd Vermont who are supported by one other regiment.   The result is a repulse.   The confederates have failed to prevent from Union troops from taking the center pass. 

The Confederates fall back in confusion. 

Conclusion

In five hours  approximately 18490 Union troops battle 19340 Confederate troops with estimated casualties 6783 Union and 6630 Confederates. Two Union brigade commanders and a division commander fall.  

The Union army by taking and holding all three objectives has scored a major victory and has disrupted the Confederate march on the far side of the mountain and can now pitch in. 

On a purely gaming note: The two Confederate charges on the last turn saw 12 total regiments charge four. In both cases during the dice down for impact the Union side could only break the charge by rolling double ones.  Both did.   The gaming group “engineer” says that’s a 1/1296 probability.  The “actuary” was silent on the matter.  

The Battle of Novice Mountain Part 2

 The day starts to heat up after the Confederates try to block the Union attack launched earlier.  The Union right continues to push against the Confederate left while only probing the center.  On the Union left it’s the rebels who arrive late but come in swinging. 

3:20pm-5:20pm

Tyler’s Division pushes against Hood’s Division who holds a stout position behind a stone wall. Tyler sends the Brigade of Phelps to the right of the wall to try to flank Hood but Kemper’s Brigade of Virginians arrive on the field in time to check the move.

An exchange of volleys on the Confederate left. 

Kemper aggressively charges Phelps’ Midwesterners but is thrown back in disorder. Phelps sees advantage and launches his own assault that hurls Kemper back causing one regiment to route (but later rally) and the rest of the Virginians to fall back.   The boys in blue are themselves in disorder from the charge and two Confederate batteries add to the confusion by firing into the reforming troops to further try to check them.   The wall continues to swirl with smoke as the Confederates fire volleys into the Union troops in front of them   Three Union batteries add to the return fire but the wall lessens the casualties.  The Union right still holds the pass and remains stuck in.

In the center, two Union Brigades belatedly advance on D.R. Jones partially arrived Division but the hesitant advance allows Jones to bring his second Brigade up.  When the Union Brigades enter musket range near a fence across their path they are met with volleys from the Confederates waiting there  

Muskets and cannon open up on the advancing Yankees.

It’s on the Union left flank where the action is most violent.   McClaws Division will sustain 2520 casualties in the first three hours and twenty minutes; more than the other two Confederate Divisions combined.

Holding behind a stone wall flanked by woods on either side New York and Pennsylvanians of the Irish Brigade supported by a battery of guns pour heavy fire into attacking South Carolinians and Mississippians as they advance on the wall  

Fire Zouaves anchor the line until contact. 

The South Carolinians take a heavy pounding approaching the wall but Barksdale’s Mississippians and Semmes’ Georgians score a breakthrough into the yard of a farmhouse behind the wall.   Artillery horses are shot down but Battery E of the U.S Artillery blasts the rebels with Canister taking a heavy toll as the Confederates cross the wall. Small Union counter charges pick up prisoners but the two Zouave regiments route from the yard.   Other Union regiments held in reserve volley into the once exuberant-now disordered Mississippians  and  Georgians.  

The wall is breached but reserves approach. 

The Union left is now a swirling and disordered brawl. 

In three hours and twenty minutes approximately 18490 Union troops battle 19340 Confederate troops with estimated casualties of 4090 Union and 4110 Confederates.

Next: The decisive hours.  

The Battle of Novice Mountain Part I

 Inspired by the Battle of South Mountain, this game of ACW using the Johnny Reb rule set represents the Union forces of General Hooker’s First Corp attempting to push through the gaps of the lesser known (some would say unknown) Novice Mountain in order to catch the Confederates marching strung out along the far side.  James Longstreet’s Corp must hold back the Union troops until nightfall thus allowing the rest of the army to clear the gaps.

   The scenario begins at 2pm with two brigades of Union troops attacking two Confederate Brigades across three passes of Novice Mountain.  Three objectives are located on the far crest of the mountains, one on each road that crosses one of the passes.   Six additional Union Brigades are scheduled to arrive starting at 3:20pm while seven Confederate Brigades are scheduled to arrive starting at 4:40pm.  Each turn  represents 20 minutes.

2pm-3:20pm

On the Union right the Division of Daniel Tyler is aggressive and marches forward against the Confederate Division of John Bell Hood.  Evans’ Brigade of Rebels gains a stone wall as Phelps’ Brigade of Yankees gains the objective  

D.R. Jones’ Confederate Division moves up the Confederate center and takes the second objective but no Confederates are to be found on the Confederate right as James Ricketts’ Division pushes through the gap to the objective on the Union right.

Layfatte McClaws arrives early due to some some good fortune and starts to move up the Confederate right to meet Ricketts. Abner Doubleday marches up the Union center but does so timidly and stops at a stone wall out of range of all but the longest cannon fire and well short of the objective.

Looking out from the Confederate center.

On the Union right Phelps’ Brigade of Tylers’ Division pitches in setting off a tripwire of cannon and musket fire from the Confederates behind the stone wall. The second Michigan routs under the withering fire but the first Louisiana who don’t have the benefit of the wall and who hold the farthest left flank of the Confederate line take a heavy punishment   They stand their ground.   More Union and Confederate Brigades arrive on that end of the field.

The Confederate left explodes. 

In one hour and forty minutes approximately 14000 Union troops battle 13000 Confederate troops with estimated casualties of 630 Union and 660 Confederates.

Next: The battle heats up
