Having fiddled around with the ACW rules a bit more, time to try them out with players. I thought I'd run Bakers Creek/Champion Hill again, but this time a proper historical scenario. This is based on the scenario in the Fire and Fury ACW book. Briefly, in 1863 the US were trying to open up the Mississippi to allow them to strike into the heart of the Confederacy but were stopped by the fortress at Vicksburg. Eventually Grant bypassed Vicksburg and mounted a raiding campaign east of the river. Johnson tried to concentrate his forces to defeat Grant, but the Union managed to bring Pembertons Corps to battle before it linked up with the rest of the Confederate Army.
Battlefield from the south. Champions Hill is on the left, Vicksburg is some miles to the west while Jackson is to the east. the short section of rail line visible is the Jackson-Vicksburg railroad, which crosses Bakers Creek.
Pembertons Army, mainly facing east. He was aware of Grants approach and took up a strong position on the ridge, the crossroads on the rise (the actual 'Champions Hill') was fortified.
Loring and Bowens Divisions. The units are generally brigades for the CSA, each stand is around 1000 men. Bowens division was small, so only has single stand. Jim commands Loring while John A has Bowen and is also CinC.
Stephensons Division (Tim) has three brigades up on Champions Hill. Pemberton can be seen directing operations and there are various baggage trains etc in the rear. The CSA win by avoiding the destruction of their army, and it may be advantageous to retreat off the table at some point. Historically Grant attempted to encircle and utterly destroy them. They are all experienced troops, and their breakpoint is 16.
Grants pinning force is McClernands XIII Corps with a division attached from Shermans XXI Corps. 9th and 10th Divs are commanded by Mark and Ian, with Simon taking over on Wednesday. Jerry has Blairs 2nd Div from Shermans Corps (with a white dot) in reserve, and 14th Div also enters later in the day.
Historically McClernands Corps was very reluctant to engage and allowed Pemberton to escape, some people speculate it may have been deliberate as McClernand had a strong rivalry with Grant. I'm treating XIII Corps has having 'poor staff; until 2pm when a staff stand enters, which will hamper their activation.
Grants brilliant manouvre had been to find an open flank around the hill - it looks pretty obvious on the table but irl it was harder to find. Champion House was a small farm near the river crossing. The two lead divisions of McPhersons XVII Corps are here (Terry), as is the veteran 12th Div (Jerry) from XIII Corps. US Grants (John B) is personally supervising operations.
Oddly the V&B scenario starts with the CSA having responded to the flanking manouvre. I've reset it so the CSA are facing east, the US have one good chance to hammer Pemberton in the flank and they'd better make the most of it as while Grants army overall is larger, they are outnumbered locally.
The rest of XVII Corps comes straggling on later in the day, John B has these as his strategic reserve. The Union Army is quite big with a starting breakpoint of 16, rising to 22 as reinforcements arrive.
The Union has quite complex victory conditions, they need to drive all non-spent CSA troops off the table in 10 turns (hours), but if they exhaust the CSA Army and and expend or destroy four CSA units they get a decisive victory. Under some circumstances it would be worth the CSA voluntarily leaving he table.
Right, to battle!
Grant directed an aggressive advance so XVII Corps simply charged at the ridge, covered by their artillery. Despite McClernands reluctance to engage, all the divisions of XIII Corps managed to activate and rolled forward into long range, again covered by their artillery. Blairs 2nd division also came marching on up to the Union gun line.
The CSA seemed somewhat thrown into disarray by this manouvre, and while two brigades of Stevensons division fired, the third (Taylors) marched northwest to protect the flank of Barton. All well and good but now Bowen crowded onto Pembertons command post on Champions Hill, blocking the retreat of every single one of Stevensons brigades.
Loring also seemed keen to take part in the action, despite one brigade dithering and his whole division swung northwest, apparently oblivious to the three Union divisions to the east.
Hard pounding time! As in any ACW battle, a lot of firing now broke out. In the north Hoveys veterans took heavy losses from the entrenched CSA and fell back to the woods. In the east 9th and 2nd Union divisions pushed forwards, covered by 10th Div.
Up on the ridge Taylor also took heavy losses under close range fire, but was unable to retire being blocked by Bowen, so lost an extra base. Realising their peril, Bowen slipped west along the road. Loring now noticed Blair and his brigades swung east again. Sadly one had failed its activation check so could only pivot in place.
Grant kept attacking. Hovey rallied easily back in the woods and Logans Brigade marched up onto the the ridge in the far west. Heavy Union fire caused Cummings to fall back to Pembertons command post up on the ridge and 10th Div followed up, also gaining a Union foothold on the ridge.
The CSA were now once again in a very unmilitary 'pudding' formation with everyones retreat routes blocked apart from Bowen,
Further south, Blairs 2nd Div was dithering east of the stream and began exchanging fire with Lorings Division, now laboriously marching back to its previous positions!
Sadly for the Confederates, the 'pudding' formation didn't prove very resiliant. Taylors brigade lost another base and was unable to retire due to being hemmed in on all sides and disintegrated. Barton up in the trenches had exactly the same problem under fire from three sides and blocked in by Cummings. They were reduced to a single base and became spent.
Bowens firefight with Logans 3 Div was also going the wrong way as they were blocked in by Lorings Division and reduced to two bases.
Faced with the impending encirclement and destruction of his army (Grant need to expend or destroy four CSA units for a decisive victory), Pemberton decided to cut and run. Bowen and one of Lorings brigades broke contact and retired over Bakers Creek to the west. Tilghman fell back towards the camp, aided by the whole of McClernands XIII Corps failing their activation tests.
Bartons Brigade were left in the fortifications as a rearguard against XVII Corps. They were doomed anyway.
Barton duly succumbed to massed Union fire, and Hoveys veterans overran the position at bayonet point, exploiting along the ridge to clear Champion Hill. Logans 1st Brigade and Blair also advanced and managed to partially surround Tilghman, whose position was now looking dire.
Pinned by ZOC they retired to the Confederate camp, accompanied by General Pemberton.
The Union units shot them up, destroying another base and they promptly failed their morale test (Pemberton declined to rally them under fire) and retired westwards too. Blair followed up and occupied the Confederate camp.
With three CSA units destroyed or spent and the others driven from the playing area, Grant has won and the whole thing was wrapped up by 4pm. Grant was however denied his decisive victory, as Pemberton slipped away to the west, just as in real life.
Well, that cracked along, and as I said in the commentary, I think the Rebs suffered an actual morale collapse in the face of the aggressive Union attack and fell into a degree of confusion. The situation might have been retrievable if they had fallen back behind the reverse slope (as Pemberton did irl), but given the ferocity of Grants attack, they may have been inviting total destruction.
Hats off to Grant (John B) for managing such a decisive result, and another hat off to Pemberton (John A) for taking the brave decision to withdraw. Posthumous medals to Barton for fighting to the last man on Champions Hill.
Many thanks to all the players for their enthusiasm and spectacular hat wearing. We shall return to the ACW in future.
