In the fluid conditions of the Somme front, with the Allies intermixed, and the British units dangerously weak and tired, German chances were still good. They made their attempt on April 24th; the capture of Villers Bretonneux was a brilliant success, but the following day the Australians recaptured it and the Germans were driven back in confusion. The battle had been fought to a standstill and the Allied Commanders-in-Chief were able to concentrate their reserves for the counter-attack which began on August 8th.
