There is some battles I really like
From polish history;

- Orsza when 20.000 Poles attacked and massacred 80.000 Russians hidden behind river.
- Obertyn - 6000 Poles massacred vs 35000 Moldavians
- Kłuszyn - 1610 - great epic battle when 6300 polish superb trained heavy cavarlymen, 200 infantrymen and 2 cannont crushed 35000 Russians, Swedens and Frenchies. Poles marched for all night in very bad terrain, fought during day and then marched to their previous position when forced to surrender another russian army ( 8.000)


And some from international history

-O'Connor's offensive in 1940
-Sedan battle
-Wiaźma 1941 - Germans teached Russians what means "surrounding"
