Are we to infer from this that Pitt and his cousin looked forward to a time when the monarchs could invade France with safety? Such an inference would be rash. It is more probable that they here found an excuse for postponing their decision and a means of calming an insistent visitor. Certainly they impressed Burke with a belief in their sincere but secret sympathy with the royalist cause. The three men also agreed in suspecting Leopold, though Burke tried to prove that his treachery was not premeditated, but sprang from "some complexional inconstancy." Pitt and Grenville, knowing the doggedness with which the Emperor pushed towards his goal, amidst many a shift and turn, evidently were not convinced. At this time they had special reasons for distrusting Leopold and his advisers. The Austrian Government had received a letter, dated Dresden, 27th August (the day of the Declaration of Pilnitz), stating that England promised to remain neutral only on condition that the Emperor would not withdraw any troops from his Belgic lands, as they were needed to uphold the arrangements of which she was a guarantee. This extraordinary statement grew out of a remark of Grenville to the Austrian Ambassador in London, that, in view of the unrest in the Netherlands, it might be well not to leave them without troops.[16] The mis-statement was not only accepted at Vienna, but was forwarded to various Courts, the final version being that England might attack Austria if she withdrew her troops from Flanders, and that therefore Leopold could not draw the sword against France until his army on the Turkish borders arrived in Swabia. Some were found who believed this odd _farrago_; but those who watched the calculating balance of Hapsburg policy saw in it one more excuse for a masterly inactivity.
