From site dedicated to tanks, especially in video games:

Capture: "on 2.8.1944 in early morning hours, a few Panthers from the abovementioned unit were making their way thru Warsaw (the route took them thru following streets: Górczewska-Mlynarska-Smetna-Powazkowska-Okopowa). At Okopowa street (near the old Jewish cemetery), the Panthers were ambushed by Polish rebel soldiers with firebombs (molotovs) and one tank burned out. Since two out of three vehicles were captured almost undamaged, the Polish soldiers decided to repair them and use them in combat. " Hand grenades and the Gammon bomb (British made grenade, usable against armor) were also used.

Action: "The first tank went the action for the first time during the St.Sofia hospital liberation, the destruction of local concentration camp and the assault on Police school on 5.8.1944. It proved especially useful during the concentration camp assault (contributing to the fact only one Polish soldier died during the operation), but the two other actions were paid by many more casualties. “Felek” was ordered to support the assault on the Police School, but because of an operational screw-up, the crew didn’t recieve the permission to open fire before the entire attack was underway. The building was heavily fortified and machinegun fire killed many Polish soldiers, before the Panther arrived and turned the tide. In the end, the Polish did succeed in taking both objectives (school and hospital), but the price was high."

Fate: "However, by that time the Polish situation on the Old Town was critical. Furthermore, “Felek” suffered from battery malfunctions (deemed irrepairable). It was decided to destroy the “Felek” – its ammo was transferred to “Magda”. “Magda” fought the next day too (11.8.) in support of the rebel counterattack, but it was damaged and abandoned by the Polish."
