The Austro-Russian treaty was activated in spring 1748, with 30,000 Russian troops under Prince Vassili Anikititch Repnine marching from Livonia to the Rhine via Bohemia and Bavaria to assist Maria Theresa. However, while the Russian force was marching across Germany, Maurice took Maastricht on 7 May and thus deprived the British and the Dutch of their last outpost in Flanders. Repnin only arrived at the Rhine when everything was already over.
