Chickamauga September 1863

 Time to try out my minor revisions to my version of Neil Thomas's ACW rules with the Zoom gang. This time we are off to Tennessee in 1863. After being forced out of Chattanooga, Braggs Army of Tennessee retreated across the mountains towards Atlanta.  Rosencrans pursued with the Army of the Cumberland, but became dispersed crossing the mountain passes. Bragg laid a trap and concentrated his forces to defeat Rosencrans in detail. The Union rushed to concentrate their forces along the Chickamauga Creek as Bragg struck.

This scenario is based on the one in the excellent Volley and Bayonet ACW scenario book. I've played it solo before but never with actual players.

Battlefield from the south, you can see the Chickamauga meandering through the woods. The woods are dense but the creek is fordable. There is a mill (Gordons Mill) in the southwest, which is presumably why the woodland peters out down there.

The CSA are coming on from the east and need to capture all the roads leading west and north as well as exhaust the Union army. The game lasts two days, six turns per day with an overnight segment.

Here is the table with the troops deployed. This is a BIG battle, and is using almost my entire collection of ACW infantry. The Union only start with four infantry divisions deployed and a couple of cavalry brigades, while most of Braggs army is already approaching the creek like a coiled spring.

Here is Braggs centre and right. I've colour coded the bases with dots for each corps and also marked the veteran and green units. Bragg didn't seem to believe in Corps integrity as the individual divisions are scattered all over the place. These are Hoods division (Longstreets Corps), Cheatham (Polks Corps), Forest and Walker. Bragg himself is just visible in the middle of his units.

John B is Bragg and also commands Hills and Walkers Corps. Tim has Polk and Buckners Corps while Jim has Longstreet and Forests Corps. Simon is joining on Wednesday and will take over Walker and Forest.

Cleburnes division (Hill) will enter during the day, while the other two arrive on the night of the 19th. Breckenridge (Hill) and Johnson (Longstreet).

Braggs left, heading towards the mill and the road exit at I1. This is Buckners Corps (Stewart and Preston) plus Hindman from Polks Corps. There are bridges and fords all over place. There are also quite a few hills, which can see over the woods, to a certain extent anyway.

Rosencrans left. You can just see Mintys cavalry brigade in the far distance, and on the nearby wooded ridge are 1 and 3 Division from XXIV Corps (Thomas). John A is Bragg and commands the overall Army and the cavalry. Micheal commands XIV Corps and XX Corps with Ian taking XX Corps on Wednesday.

Down at the mill we have Wilders mounted infantry brigade armed with Spencer repeaters! There are also 2 and 3 Div from XXI Corps (Crittenden). These are commanded by John for now with Mark taking over on Wednesday.

Marching to the rescue is this lot. No less than five more divisions. 2 and 4 Div from XIV Corps, 2 and 3 Div from XX Corps (McCook) and finally 1 Div from the Reserve Corps (Granger). Most of this lot march on along the southern road, but Granger will enter on the 20th in the north. Rosencrans is just visible on the end of the ridge at the top of the screen. From here he can see most of his army which will help with C3. 

Union traffic management could be interesting, but the horrible terrain in the north will delay the CSA.

The Union breakpoint is a mere 11 bases, rising to 21 as the various reinforcements turn up. The much bigger CSA Army starts with a BP of 19, rising to 25 as their reinforcements arrive. Bragg needs to strike hard and fast while he has the advantage. 

Right, to battle....

The action opened with Buckner and Polk (Tim) trying to sort themselves out a bit. The CSA pushed forward in the south, covered by their artillery on the hill as Polks stray division marched southeast to join them.  Stewart got as far as the hill behind the stream while Hindman took position in the treeline further south.

Hoods Texans moved aggressively west down the main road to keep Thomas's Corps busy, while Forest very appropriately moved into the middle of the woods. Braggs plan was to hit hard in the south, pin the centre and largely ignore the north until reinforcements arrived.  

Sadly this came unstuck when Stewart came under a storm of very accurate (lucky) fire which managed to knock a base off in one salvo, and they retired back behind the hill to recover. Rosencrans took the opportunity to push Wilders cavalry up onto the hill,  while Palmer marched up the road to hold the cavalry's vacated position.

Thomas' Corps in the north just took Hood under fire, but at long range and against cover, it was largely ineffective. The CSA responded with fire and managed to knock a few hits off various exposed Union units and Stewart rallied. Sadly Forest managed to dither, presumably lost in the forest.

In the northeast, Walkers reserve division marched north, presumably to clear away the Union cavalry. You can see the green dither marker on Forest. The players all seemed to find this very funny. Bragg had moved south to better control the southern attack, so Forest was no longer in immediate command distance and hidden in the trees.

The Union hung on tenaciously at Gordons Mill as reinforcements moved up the road from the southeast. Thomas was trying to unite the four divisions of his Corps, but unfortunately the road was blocked by Palmer, who chose this moment to dither. The firepower of the Wilders Spencer rifles came as a horrible surprise to the Confederates. Polk and Buckner seemed content to stand and shoot at long range in the south, whereas ideally they would have been closing in while the Union army was still deploying. 

Thomas (XIV Corps) by now had all four of his divisions in roughly the right place, but Jim was doing a great job of keeping them pinned with Hood and Forest. The latter had finally made his way to the treeline. Polk made a devastating attack on Wilder, inflicting no less than seven hits on the cavalry. Van Cleve had also had enough at Gibsons Mill and fell back, so Preston pushed west once again.

Both Gibson and Wilder fell as far back as they were able, and by now XX Corps (McCook) was able to support the defence of the mill, although there was a great traffic jam on the road behind. 2 Div (Johnson) involuntarily took up position behind the hill north of the mill as it dithered, although in fact the reverse slope was quite a good spot. Van Cleve failed to rally however.

Up in the north, Forest and Hood kept skirmishing with Thomas, neither side inflicting decisive losses, but the Confederates were tying up four divisions with two of their own!

Walker closed with Mintys cavalry who loosed off an ineffective volley into the forest.

With that we had to close for the night going into turn five. Unfortunately it was all taking longer than I'd hoped. A combination of the number of moving parts and player unfamiliarity with the rules which led to discussions on the various options. Maybe it will speed up tomorrow but I suspect not as we are into the 'dogfighting' stage of attrition, as Montgomery put it. 

Afternoon of the 19th saw more heavy fighting around the mill as Polk and Buckner threw their divisions forwards. The fresh XX Corps was in a decent position but still took heavy losses. Cheathams veterans hung on in the ccentre and combined with Hoods Texans, drove back Palmers inexperienced division in the centre.

In the north as night fell, the Confederates began to gain the upper hand. Although Thomas secured his right flank on the ridge, the left flank began to collapse as Palmer fell back and then Baird as the fire became too much. A dangerous hole opened up in the Union centre just as Walker finally finished off Mintys cavalry brigade after a successful bayonet charge which overran them.

Overnight, two more CSA divisions arrived and Polk assumed command of the southern wing of the Confederate Army and either dug rifle pits in place or extended the line. The Union just dug in, but Wilders cavalry finally rallied and moved back into line behind the stream. Palmer could have moved back into his old position but chose to dig in instead.

In the north Longstreet took over but both sides largely consolidated in place. Thomas rallied his Corps and dug in along and behind the ridge. You can just see the two CSA reserve divisions on the right, Breckenridge and Johnsons divisions.  Cleburne had already been allocated to Polk.

Hindman charged in the south and finally took Gibsons Mill, driving back the Union and capturing their artillery. In turn his division was destroyed by concentric fire by the Union troops entrenched in depth behind the bridge, but Breckenridge was now in place to exploit the bridghead. The entrenched CSA troops on the hill north of the mill held their positions and along with Cheatham, poured fire into the Union positions.

In the north Cleburne advanced due west and occupied the wood south of the ridge but was driven out again by fire. Walker cleared the road in the north and joined the extreme flank of the Confederate army. Thomas' Corps just hung on as best it could.

Breckenridge occupied the bridgehead again in the south while Longstreet pushed divisions forwards aggressively in the centre to exploit the gap in the Union lines.

Walker crossed the stream in the extreme north to flank Thomas, while Cleburne and Johnson held on to their foothold on an south of the ridge despite heavy fire.

In the south XX Corps was forced back from the river line, but Cleburne was also repulsed. This looked pretty much like the Confederate high water mark as losses were disproportionately mounting on the CSA side.

We were running short of of time and called it at that point. Although the Confederates had dented the Union line and inflicted heavy losses, I couldn't see them achieving their objectives in the time remaining but both sides declared honours even.

After a slow start, that actually went pretty well. I was very pleased with the rules tweaks as they all worked fine although there are still a lot of moving parts to manage. Actually running a game with people clarified some bits where I'd been unclear or made mistakes - in particular I got the sequence of morale tests in the charge sequence wrong, for which I apologise to the Union. Im minded to tone down the cover effect of dense woods, making them soft cover if you will, compared to Rifle pits etc. A break from Neil Thomas cover/not cover, but necessary I think. 

There was a certain desire expressed to try some more ACW battles, so I'll add the clarifications and tweaks to the rules and put on another game in due course.
