The Kalisz group fought in the region of Kaliska and Barska streets. It kept its positions until 10 August, when, having used up all possibilities to continue combat, withdrew to a concentration place in Chojnowo forests. After reorganisation and replacements, the unit commanded by lieutenant "Stach" returned to Warsaw and took part in combats in Wilanów, in Sadyba, in Czerniaków and in Mokotów until the end of the Warsaw Uprising.
