tons of Iraqi and Australian grain to Bengal and the war cabinet agreed to send 200,000 tons by the end of the year. During the last quarter of 1943, 100,000 tons of rice and 176,000 tons of wheat were imported, compared to averages of 55,000 tons of rice and 54,000 tons of wheat earlier in the year. In October, Churchill wrote to the newly appointed Viceroy of India, Lord Wavell, charging him with the responsibility of ending the famine. In February 1944, as preparation for Operation Overlord placed greater demands on Allied shipping, Churchill cabled Wavell saying: "I will certainly help you all I can, but you must not ask the impossible". Grain shipment requests continued to be turned down by the government throughout 1944, and Wavell complained to Churchill in October that "the vital problems of India are being treated by His Majesty's Government with neglect, even sometimes with hostility and contempt". The relative impact of British policies on the death toll of the famine remains a matter of controversy among scholars. International conferences in 1942 On 20 May 1942, the Soviet Foreign Affairs minister, Vyacheslav Molotov, arrived in London and stayed until the 28th before going on to Washington. The purpose of this visit was to sign a treaty of friendship but Molotov wanted it done on the basis of certain territorial concessions regarding Poland and the Baltic countries. Churchill and Eden worked for a compromise and eventually a twenty-year treaty was formalised but with the question of frontiers placed on hold. Molotov was also seeking a Second Front in Europe but all Churchill could do was confirm that preparations were in progress and make no promises on a date. Churchill felt well pleased with these negotiations and said as much when he contacted Roosevelt on the 27th. The previous day, however, Rommel had launched his counter-offensive, Operation Venice, to begin the Battle of Gazala. The Allies were ultimately driven out of Libya and suffered a major defeat in the loss of Tobruk on 21 June. Churchill was with Roosevelt when the news of Tobruk reached him. He was shocked by the surrender of 35,000 troops which was, apart from Singapore, "the heaviest blow" he received in the war. The Axis advance was eventually halted at the First Battle of El Alamein in July and the Battle of Alam el Halfa in early September. Both sides were exhausted
