Skirminion

From BoardGameGeek:

Skirminion is a fast, brutal, abstract wargame played on a chessboard, where every unit is a healthtracked die and every decision is life or death. Position your troops, fortify with pawns, grind down the enemy through attrition, and outmaneuver them with tactical retreats, flanking, and siege. No randomness in combat - just pure battlefield strategy.
