Berestechko 1651 is a game for two players simulating the third day of the battle of Berestechko, fought on 30th June 1651 between the Zaporozhian Cossacks, led by Hetman Bohdan Khmelnytsky and aided by their Crimean Tatar allies, and a Polish-Lituanian army under King John II Casimir, near the Styr river in Volhynia It was one of the largest land battles of 17th century Europe.
The game is a small-footprint simulation intended to give a quick and easy representation of the battle, focusing on good preparation of attacks and on when and where to withhold, retreat, rally and reorganize. The game lasts two turns. In each turn players alternate performing “impulses”, in which they activate units and/or gather coordination and reorganization commands. In each turn each unit can be activated up to two times. A turn ends when all units of one player have been activated twice. Once the second turn ends, victory is assessed, although an automatic victory can happen before the end of the two turns if certain conditions are met.
