In the meantime, Russia spent most of 1806 recovering from defeats from the previous year's campaign. Napoleon had hoped to establish peace with Russia and a tentative peace treaty was signed in July 1806, but this was vetoed by Tsar Alexander I and the two powers remained at war. Though nominally an ally in the coalition, Russia remained a dormant entity for much of the year (giving virtually no military aid to Prussia in the main battles that October, as Russian armies were still mobilising). Russian forces would not fully come into play in the war until late 1806 when Napoleon entered Poland.
