The Battle of San Pietro, also known as the Battle of Crocetta or the Battle of Parma was a battle fought on June 29, 1734, between troops of France and Sardinia on one side, and Habsburg Austrian troops on the other, as part of the War of Polish Succession, between the village of La Crocetta and the city of Parma, then in the Duchy of Parma. Austrian troops assaulted an entrenched Franco-Sardinian position, and were ultimately repulsed, due in part to the death of their commander, Florimund Mercy, and the wounding of his second in command, Frederick of Württemberg.
