On 20 May, 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 re Poland and the Baltic States. Churchill and Eden worked for a compromise and eventually a twenty-year treaty was formalized 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.
On June 23, 1942, Eisenhower returned to London as Commanding General, European Theater of Operations (ETOUSA), based in London and with a house on Coombe, Kingston upon Thames, and took over command of ETOUSA from Chaney. He was promoted to lieutenant general on July 7.
As 1942 drew to a close, the tide of war began to turn with Allied victory in the key battles of El Alamein and Stalingrad. Until November, the Allies had always been on the defensive, but from November, the Germans were. Churchill ordered the church bells to be rung throughout Great Britain for the first time since early 1940. On 10 November, knowing that El Alamein was a victory, he delivered one of his most memorable war speeches to the Lord Mayor's Luncheon at the Mansion House in London, in response to the Allied victory at El Alamein: "This is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning".
