began to intern Germans and suspected collaborators. Czech noncombatants assisted by setting up makeshift hospitals for the wounded and bringing food, water, and other necessities to the barricades, while German forces were often resorted to looting to obtain essential supplies. Czech forces seized thousands of firearms, hundreds of Panzerfausts, and five armoured vehicles, but still suffered a shortage of weapons. By the end of the day, the resistance had seized most of the city east of the Vltava River. The insurgents held many important buildings, including the radio, the telephone exchange, most railway stations, and ten of twelve bridges. Three thousand prisoners were liberated from Pankrác Prison. By controlling the telephone exchange, resistance fighters were able to sever communication between German units and commanders.
