Pick two forces. Divide a rectangular table in half with an impenetrable river with a bridge in the middle. One force is A, the other B. Corners are 1,2,3,4. Start the forces as follows: (Give A1 some relic or something to protect and get off the table at A4).
A1
.B2
3/4 cavalry from A
.1/3 cavalry from B
1/4 infantry from A
2/3 infantry from B
xxxxxxxxxxxxxxxxxxxxxxxx bridge xxxxxxxxxxxxxxxxxxxxxxxxxxx
B3
A4
2/3 cavalry from B
.1/4 cavalry from A
1/3 infantry from B
3/4 infantry from A
A1 has to exit table at A4, only way across the XXX is the bridge so everyone has secure flanks. A4 will try and help A1 escape. B3 and B2 will try and destroy A.
Played it last night with A as Crusaders and B as Saracens (the river was shifting sand with a pass in the middle, no cover anywhere on the table). A1 70% losses, A4 50%, B1 destroyed, B2 40% losses. A1 had a holy relic so A won as they got it off the table

We use our own rules but its there to try if you want,
