What happened May 1942 AD in United Kingdom

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.

Churchill felt well pleased with these negotiations and said as much when he contacted Roosevelt on the 27th.
