In the affinity for error of German diplomats, these judgments established a record.

From the Guns of August by Barbara Tuchman.

Now that the moment had come, the Kaiser suffered at the necessary risk to East Prussia, in spite of the six weeks’ leeway his Staff promised before the Russians could fully mobilize. “I hate the Slavs,” he confessed to an Austrian officer. “I know it is a sin to do so. We ought not to hate anyone. But I can’t help hating them.” He had taken comfort, however, in the news, reminiscent of 1905, of strikes and riots in St. Petersburg, of mobs smashing windows, and “violent street fights between revolutionaries and police.” Count Pourtalès, his aged ambassador, who had been seven years in Russia, concluded, and repeatedly assured his government, that Russia would not fight for fear of revolution. Captain von Eggeling, the German military attaché, kept repeating the credo about 1916, and when Russia nevertheless mobilized, he reported she planned “no tenacious offensive but a slow retreat as in 1812.” In the affinity for error of German diplomats, these judgments established a record. They gave heart to the Kaiser, who as late as July 31 composed a missive for the “guidance” of his Staff, rejoicing in the “mood of a sick Tom-cat” that, on the evidence of his envoys, he said prevailed in the Russian court and army.
