 In Alexandria, Farouk appealed to Caffery for help, accusing the Free Officers of all being Communists.Despite the stained relations with Britain, Farouk also appealed to Britain to intervene; the "Black Saturday" riot had convinced the Churchill government that to intervene in Egypt would entail guerrilla warfare in the Nile river valley, which ruled out intervention.Ali Maher, who sided with the Free Officers and was appointed prime minister by them, arrived in Alexandria on 24 July to tell Farouk that the Free Officers wanted Nagiub to be War Minister and the dismissal of his "kitchen cabinet".
