Battle of Modlin

The Battle of Modlin took place during the German invasion of Poland at the beginning of the Second World War. Modlin Fortress was initially the headquarters of the Modlin Army until its retreat eastwards. From 13 September to 29 September 1939 it served as a defensive citadel for Polish forces under the command of General Wiktor Thommée against assaulting German units. This fighting was closely linked with the strategic situation of the Battle of Warsaw.

The Polish forces defending the fortress included the armoured train Śmierć ("death") and the Modlin anti-aircraft battery, which was credited with shooting down more Luftwaffe planes than any other in the entire September campaign.

Fortress Modlin capitulated on 29 September, one of the last to lay down its arms in the campaign, surrendering 24,000 troops. Several days earlier, Rochus Misch attempted to negotiate the surrender of the fortress despite being wounded, an act for which he was awarded the Iron Cross.

Men from Panzer Division Kempf committed the Massacre in Zakroczym on 28 September 1939.
