As the British refused to leave their base around the Suez Canal, the Egyptian government cut off the water and refused to allow food into the Suez Canal base, announced a boycott of British goods, forbade Egyptian workers from entering the base and sponsored guerrilla attacks, turning the area around the Suez Canal into a low level war zone. On 24 January 1952, Egyptian guerrillas staged a fierce attack on the British forces around the Suez Canal, during which the Egyptian Auxiliary Police were observed helping the guerrillas. In response, on 25 January, General George Erskine sent out British tanks and infantry to surround the auxiliary police station in Ismailia and gave the policemen an hour to surrender their arms on the grounds the police were arming the guerrillas. The police commander called the Interior Minister, Fouad Serageddin, Nahas's right-hand man, who was smoking cigars in his bath at the time, to ask if he should surrender or fight. Serageddin ordered the police to fight "to the last man and the last bullet". The resulting battle saw the police station levelled and 43 Egyptian policemen killed together with 3 British soldiers. The Ismailia incident outraged Egypt. The next day, 26 January 1952 was "Black Saturday", as the anti-British riot was known, that saw much of downtown Cairo which the Khedive Ismail the Magnificent had rebuilt in the style of Paris, burned down. Farouk blamed the Wafd for the Black Saturday riot, and dismissed Nahas as prime minister the next day. He was replaced by Aly Maher Pasha.
