Game 3 vs Anton Verster, Mongol Conquest
The Mongols invaded, placing gentle hills and open fields and I put down a difficult hill to constrain his movement, a BUA to protect my baggage and some rough going for the Slavs to hide in. The Mongols had to deploy first and there was a strong wind.
Anton placed 4 artillery on a gentle hill in the centre front of his deployment area with 6 CvS behind. On either side of this CinC's command were two LH subgenerals each with 16 LH. 3 Army baggage lurked at the rear. I deployed my CinC in the centre, Khagan's cavalry on the right and Slavs on the left, where a boggy flat gave them some protection. The Khagan's command was thinly stretched, but they were only up against light horse, so what could possibly go wrong?
The Mongols began in customary fashion by moving columns outside my flanks and generally advancing with the rest of the light horse. The guard cavalry formed column and shifted to support the attack against my right.

I marched the Khagan's command up to threat zone the Mongols to their front and prevent them from escaping. One element was detached to delay the flanking troops. The Bulgars advanced to support the Khagan's cavalry, but the march move-stopping effect of the Mongol guards left them slightly set back from them. The Khazar Nobles moved to the right with a view to joining in against the guards. I also wheeled some artillery to shoot at the guards, but came within reach of an element of Mongol light horse that promptly attacked and destroyed some bolt shooters.
Meanwhile the Mongols on the right decided to charge rather than try to run away. It was +2 vs +3 against them all the way down the line, except in front of the Bulgars, where they had an overlap. They then proceeded to win every combat, destroying three of my elements, except in the last combat, in which the Mongols died.

With only 2 reserves and 3 holes, I couldn't fill all of them and decided I would be better off sending one element behind the Mongol line instead of plugging a gap. The rest of the cavalry attacked, my sub-general engaging the Mongol sub-general. The Bulgars joined in the attack and the Nobles turned into line ready to advance on the Mongol guards. This counter-attack eliminated three more elements for the loss of one CvS, but left a large number of flanks and rears exposed, including that of the subgeneral.
On the left, I sent an ordinary cavalry element forward to pin the enemy while a superior one attacked the element that had just destroyed the bolt shooter. I only inflicted a recoil.

Unfortunately, I had underestimated the distance and an unpinned light horse reached the rear of the CvS. Luckily the cavalry destroyed the Mongol element in front of it. However, the “forlorn hope” CvO was destroyed by a frontal attack.
On the right, the Mongol light horse, with the high dice, swarmed all over the Khagan's command and wiped out all except three of its remaining elements and the guards destroyed one of the Bulgars.

Oh well, surely just a temporary setback as the Nobles were nearly in position to attack the Mongol guards and the cavalry of the Slav command were also in attack range. As I was throwing my two remaining PIP dice, Anton commented “A double 1 would be handy here”. “Yes”, I said and lifted the dice cup to reveal … double 1. “Sorry” said Anton, not that he was in any way responsible for the dice result.
This limited my counter-attacks, It's not entirely clear from the photos what happened in the next few bounds, but I did manage to kill one element of guards by a hard-flank and another one seems to have disappeared from the pictures for no apparent reason, so I suspect the wind dropped and he died to artillery shots. Meanwhile, the Nobles went off on spontaneous advances, one group surviving artillery(S) shots to press forward, but not quite into contact (240p + 40p for sponno not making contact + 60p press forward!), but another element died to a front and flank attack. On the left I had somehow accumulated 4 kills on the other light horse command, only 1 short of disheartening them. We also had the unexpected sight of a broken cavalry element routing towards the _enemy_ rear table edge.

In the next bound Anton was able to use rear and/or flank contacts to destroy more nobles, another element of Bulgars and the CinC to break that command and the army. 23-2 again, but this time it was me with the 2. Quite an interesting game with the large central area interdicted by both sides' artillery. While I had bad luck in this game, the impact of it was increased by a number of mistakes that I made.

While packing up after this game I realised that I had been deploying the Slav command with the cavalry component of the analogous command in the Ghaznavid army, i.e. 3 CvS + 4 CvO instead of its proper complement of 3 CvS + 3 CvO. I had been using the correct break points, however. I reported this to our illustrious umpire, Doug, who said “Don't tell anyone”. This wouldn't have had any material impact on the second or third game, but might have made a difference in the game against Doug as the CvS would have been slightly more exposed to his attacks.
