In January 1920 Curzon insisted that British troops remain in Batum, against the wishes of Wilson and the Prime Minister. In February, while Curzon was on holiday, Wilson persuaded the Cabinet to allow withdrawal, but Curzon had the decision reversed on his return, although to Curzon's fury (he thought it "abuse of authority") Wilson gave Milne permission to withdraw if he deemed it necessary. At Cabinet on 5 May 1920 Curzon "by a long-winded jaw" (in Wilson's description) argued for a stay in Batum. After a British garrison at Enzeli (on the Persian Caspian coast) was taken prisoner by Bolshevik forces on 19 May 1920, Lloyd George finally insisted on a withdrawal from Batum early in June 1920. For the rest of 1920 Curzon, supported by Milner (Colonial Secretary), argued that Britain should retain control of Persia. When Wilson asked (15 July 1920) to pull troops out of Persia to put down the rebellion in Mesopotamia and Ireland, Lloyd George blocked the move, saying that Curzon "would not stand it". In the end, financial retrenchment forced a British withdrawal from Persia in the spring of 1921.
