The Dalmatian Campaign saw several battles fought between 30 April and 21 May 1809 by Auguste Marmont's First French Empire soldiers and Andreas von Stoichevich's Austrian Empire troops. The Austrians drove the French from their positions on the Zrmanja River at the end of April. But in mid-May, the French counterattack forced back the Austrians. The defenders offered stout resistance, but ultimately Marmont broke out of Dalmatia and joined Emperor Napoleon's army near Vienna with over 10,000 men. The campaign was fought during the War of the Fifth Coalition, part of the Napoleonic Wars. Dalmatia is part of the modern-day nation of Croatia.
