The Austro-Hungarian leadership is confused by conflicting messages from Berlin on whether to order general mobilisation or not. Bethmann Hollweg seems to be saying to proceed just with partial mobilisation against Serbia and to give diplomacy a chance while Moltke is urging general mobilisation against both Serbia and Russia.
Conrad is the Austro-Hungarian most keen on general mobilisation. At a council of war attended by Franz Josef, Berchtold and Tisza he carries the day. Austria-Hungary will proceed to general mobilisation. But in true Austro-Hungarian style, general mobilisation will not begin until the 4th of August. And the question of whether mobilisation is being made against Serbia and Russia or just Serbia is left undecided for now.
