Morning: Jules Cambon sees Jagow. Cambon says if there is war England will stand by France and Russia. Jagow replies “You have your information. We have ours which is quite to the contrary. We are sure of English neutrality”.
Jagow is worried by early signs of Russian military preparations. He tells Cambon “We shall mobilise at once either if Russia mobilises on our frontier or if Russian troops invade Austrian territory”. Cambon immediately passes this information to the Russians who take it to mean German acceptance of Russian partial mobilisation against Austria-Hungary only.
