With the British out of the way, the Germans began their final push against France. By June 12, German tanks had broken through the main fronts along the Somme River and the fortified Maginot Line, moving ever closer to their goal, Paris. During this time, the British vigorously encouraged France to resist at all costs. The new British prime minister, Winston Churchill, even flew to Paris himself to offer his personal encouragement. At the same time, though, the British government denied French requests for military assistance, wanting to conserve strength for Britain’s own defense in the near future.By this time, the size of the French army had been reduced by roughly half, and French leaders became resigned to an inevitable surrender. On June 22, 1940, France signed an armistice with Germany. Hitler insisted that it be done in the same railway car in which Germany had surrendered to France in 1918, at the end of World War I. On June 23, Hitler flew to Paris for a brief sightseeing tour of the occupied city, during which a widely published photo was taken of Hitler standing against the backdrop of the Eiffel Tower.
