In a battle with Hungary last night, I had Critical matchups between Sac militia and some mailed nights and an enemy generals unit.

I had to fight two mixed unit stacks, one about 2/3 strong and one 1/2 strong, with a 3/4 sized stack of my own mixed stack including 3 trebuchets and a catapult.

The way the battle played out, I had my SMs set to guard mode in front of the artillary, and the Hungarian general and a unit of mailed knights from the re-inforcement army both got off great charges into those lines. I had 3 units in 5 deep formation set to guard mode. 2 of them got hit hard by the charge, but held, and I managed to flank the general with the 3rd, and surprisingly, they all held the line until I managed to get my general and 2 siphais into that fight. They were pretty far away though, and the SMs did manage to hold the line and protect the arty for a good bit of time without much help. If the enemy cav had gotten through to the Artillary, I'm certain I would have lost the battle outright. Battle difficulty is VH, and this is much better performance than I usually get out of SMs vs. cav, so I attribute it mostly to the guard mode thing. But who knows if there was other factors in play (fatigue, exp, command stars, etc.)
