The siege of Mainz (3 January – 4 May 1814) saw an Imperial French corps under Charles Antoine Morand besieged in Mainz Fortress by an Imperial Russian corps led by Louis Alexandre Andrault de Langeron. When the Russians left in February 1814, they were replaced by the V German Corps, led by Duke Ernest of Saxe-Coburg and made up of the soldiers from the County of Nassau, the Duchy of Berg and several other minor German states. The French were far too strong for the Allies to directly attack the fortress. However, an outbreak of typhus ravaged the city. Despite the epidemic, Morand did not surrender the city until the news of Napoleon's abdication arrived.
