The carefully coded word in the agreement proved no less catalytic for the other European powers. The results were absolute chaos. Empress Elizabeth of Russia was outraged at the duplicity of Britain's position. Not only that France was so enraged, and terrified, by the sudden betrayal of its only ally. Austria, particularly Kaunitz, used this situation to their utmost advantage. The now-isolated France was forced to accede to the Austro-Russian alliance or face ruin. Thereafter, on May 1, 1756, the First Treaty of Versailles was signed, in which both nations pledged 24.000 troops to defend each other in the case of an attack. This diplomatic revolution proved to be an important cause of the war; although both treaties were self-defensive in nature, the actions of both coalitions made the war virtually inevitable.
