The second war lasted from 648 to 695. One of the main battle grounds of this conflict was Dos Pilas, now a separatist kingdom led by B'alaj Chan K'awiil, under Calakmul's dominance. Supported by his new allies, B'alaj Chan K'awiil consequently began a destructive "proxy war" against his old mother city. In 672, Tikal retook Dos Pilas, but B'alaj Chan K'awiil escaped to Aguateca. He rallied his followers and allies, and launched a counter-offensive, defeating the army of Tikal in a major battle in 679.
