Friedrich Franz Xaver Prince of Hohenzollern-Hechingen was an Austrian general. He joined the Austrian military and fought against the Kingdom of Prussia, Ottoman Turkey, and the First French Republic. He was promoted to the rank of general officer during the French Revolutionary Wars. During the Napoleonic Wars, he led a division in 1805 and an army corps in 1809. He was Proprietor (Inhaber) of an Austrian cavalry regiment from 1802 to 1844.

The Battle of (the) Trebbia was fought near the rivers of Tidone, Trebbia, and Nure in northern Italy between the joint Russian and Habsburg army under Alexander Suvorov and the Republican French army of Étienne-Jacques-Joseph-Alexandre Macdonald. Though French forces were moderately more numerous, the Austro-Russians severely defeated the French, sustaining about 5,500 casualties while inflicting losses of 16,500 on their enemies. The War of the Second Coalition engagement occurred west of Piacenza, a city located 70 kilometres (43 mi) southeast of Milan.
