With the Austro-Hungarian government on the same page at long last, it remained to follow through with the ultimatum. To Berchtold, this meant moving as quickly and as secretly as possible, so that once the ultimatum arrived in Serbia, Europe would be presented with a fait accompli. The Germans were similarly anxious, and emphasised the necessity of speed. Still, neither Berlin nor Vienna gave much thought to the Russians. Somehow, a comfortable consensus permeated: Russia would not defend Serbia, but if she did, this was the best time to fight her. The more surprised Russia was, the more likely she was to be overtaken by events. Thanks to Berchtold's carelessness and cracked Italian codes, however, the secret did leak out. Here we examine how this happened, and what it meant for the deteriorating situation.
