17th July, 1945: Allied leaders gather at Potsdam

The leaders of the three Allied nations have gathered in the German city of Potsdam to decide the future of a defeated Germany.
British Prime Minister Winston Churchill, US President Harry S Truman and leader of the Soviet Union Josef Stalin, accompanied by senior ministers and military staff, are conducting a systematic review of the political and economic situation in Europe.

The main aims of the conference are:

to establish the future control of Germany

to decide how to disable certain industries in Germany so that the country cannot rise up against its neighbours again

to ensure delivery of food and raw materials to a liberated Europe ravaged by war and in danger of famine

Adequate shipping is desperately need to bring in supplies, but allied ships are currently in demand in the Pacific region where fighting is continuing.
The war in the Pacific will certainly be high on the agenda.

Earlier this year the Soviet Union broke its treaty of friendship with Japan and the Japanese are hoping the USSR will not get involved in the war in the Far East.

In the last few days US battleships and swarms of planes have been bombarding Japan's industrial cities.

The Japanese, crippled by defeats on islands off the Philippines last October, have been slow to respond and even the infamous suicide aircraft have been conspicuous by their absence.

Churchill visits Hitler's bunker

There is tight security around the conference which is being held in a secret location and guarded by thousands of British, American and Soviet troops.

Earlier today, Mr Churchill and President Truman each visited the shattered German capital, Berlin.

Mr Churchill, accompanied by Foreign Minister Anthony Eden and his daughter Mary Churchill, was greeted at the Brandenburg Gate by Colonel-General Gorabotov, the Soviet Military Governor of Berlin.

The US President was driven in the summer heat through battle scarred avenues and past refugees camping out on the roadside.His car stopped at the ruins of the old Reichs Chancery from where Hitler made his speeches.

He declined an invitation by Soviet Major-General Sidnev to inspect the building and drove on.

When Mr Churchill arrived, he was also greeted by the major-general, and his party got out of the car and walked through a crowd of amazed onlookers whispering: "It's Churchill, see the cigar."

He inspected the damaged walls of the building and was then driven by jeep to see the interior. The British group then visited the Fuhrer's room on the first floor and Hitler's legendary bunker.

He was also shown the spot where the bodies of Hitler and Eva Braun were said to have been burned.

When he emerged from the Chancery, the prime minister was cheered by a group of British sailors and Royal Marines who were also visiting the war-torn city, and then returned to Potsdam.
