The Battle of Trzciana (also known as Battle of Honigfelde or Battle on the Stuhmer Heide) took place in late June 1629 (usually said to be 27th in the New Style calendar) and was one of the battles of the Polish-Swedish War (1626–1629). The Polish forces were led by Crown Field Hetman Stanisław Koniecpolski and imperial troops under Hans Georg von Arnim-Boitzenburg, sent by emperor Ferdinand II to aid Sigismund III, met with troops commanded by Swedish King Gustav II Adolf, who supported the Protestant Lutherans of Germany and northern Europe. Fighting in Prussia continued after the battle into July and August and ended with stalemate and finally a truce accepted by Sigismund III.
