The Battle of Bassignana saw a Russian corps led by Andrei Grigorevich Rosenberg, who was under the influence of Grand Duke Constantine, attempt to establish a bridgehead on the south bank of the Po River in the presence of a French army under Jean Victor Marie Moreau. The French rapidly massed superior strength and attacked. After several hours of hard fighting, the Russians abandoned their foothold with serious losses. This War of the Second Coalition action occurred near the town of Bassignana, located in the angle between the Po and Tanaro Rivers, about 19 kilometres (12 mi) northeast of Alessandria, Italy.

Diederich Arend von Rosenberg or Andrei Grigoryevich Rosenberg was an Imperial Russian general who led troops against Ottoman Turkey, the Polish–Lithuanian Commonwealth and Republican France. During the War of the Second Coalition he capably led an army corps under the famous Alexander Suvorov at Cassano, Bassignana and the Trebbia. In addition, his advance guard fought at Gavi when pursuing retreating French troops after the Battle of Novi. During Suvorov's Swiss campaign, Rosenberg's column took the Oberalp Pass around Lake Oberalpsee; while in independent command, he and his rearguard badly defeated a French force under André Masséna in the Battle of the Muotatal (Muottental/Muttental) on 30 September – 1 October 1799.
