The Swedish king returned to Polish Prussia with substantial reinforcements in May, and marched south towards Graudenz (Grudziądz) hoping to cut-off Arnim's newly arrived imperial corps before it could join Koniecpolski. He was unsuccessful, and while withdrawing north towards Swedish garrisons in Stuhm (Sztum) and Marienburg (Malbork) he was drawn into battle on 27 June 1629 at Honigfeld(t) or Honigfelde near Stuhm, in an action known to the Poles as the Battle of Trzciana. In this encounter, while attempting to cover the withdrawal of his infantry, Swedish cavalry were subjected to a series of fierce engagements at the villages of Honigfeldt, Straszewo and Pułkowice. With the aid of Arnim's heavy cuirassiers the Poles with their faster 'winged' hussars and cossack mercenaries were able to gain a great advantage over the light Swedish horsemen. Swedish losses in the fight were heavy, amounting to 600 or 700 killed, almost all of which were cavalry (including Herman Wrangel's son). The Polish took 300 prisoners, 10-15 standards, as well as 10 of Gustavus Adolphus' famous leather cannon. Commonwealth losses were under 300 killed and wounded. The Swedish king himself barely escaped with his life and later said he had never taken "such a hot bath".
