Trotsky's speeches and agitation incurred the wrath of German officer inmates who complained to the British camp commander, Colonel Morris, about Trotsky's "anti-patriotic" attitude. Morris then forbade Trotsky to make any more public speeches, leading to 530 prisoners protesting and signing a petition against Morris' order. Back in Russia, after initial hesitation and facing pressure from the workers' and peasants' Soviets, the Russian foreign minister Pavel Milyukov was compelled to demand the release of Trotsky as a Russian citizen, and the British government freed him on 29 April 1917.
