          Armed Forces Day. The soldiers are celebrating the Feast of the Polish Armed Forces.

          The Germans, for the first time in the battle, use their heaviest mortar "Karl" (caliber 600 mm, weight 1200 kg). First shells fall on Śródmieście.

          "Prudential", the highest building in Śródmieście, is under heavy fire.

          The Germans launch a fierce attack in order to storm and overrun the north-west line of defense of the Old Town. The insurgents manage to keep their positions, but with great difficulties. In the evening the enemy secures the Mostowski Palace. Once more the troops of "Parasol" and scout battalion "Wigry" move into the fray. Both armies fight in close contact. The Germans, bombarded with grenades, finally pull back.

          The Germans are storming the area of Żelazna, Grzybowska, Sienna and Prosta Streets, but their attacks are successfully repelled by the troops of "Chrobry II" and "Hal".

          Fierce fights over the positions on Krochmalna Street are ongoing - the area passes from hand to hand.

          The intense fights in the area of north-west Śródmieście last the whole day. Subsequent houses change hands a number of times. In the evening the Germans retreat to their initial positions, losing at least 150 men. 5 tanks are destroyed.

          The Home Army squad secures the building at 23 Aleje Ujazdowskie, held by the SA company.

          A new Home Army battalion "Rum" is formed.

          The "Jeleń" ("Stag") unit mans the Dąbrowski Legions Fort.

          Soviet planes are bombing the Okęcie Airport under the control of the Germans.

          The information bulletin begins to publish lists of missing persons.

          At night, Allied planes from the Italian base Brindisi deliver drops of weaponry. Three planes are shot down over Warsaw.
          One of them, with the Canadian crew on board, goes down in flames and crashes near the insurgent barricade on Miodowa Street. All the airmen die. The insurgents disassemble a cannon from the plane.
