Battle of Marengo order of battle

The Battle of Marengo (14 June 1800) was fought between the French army of First Consul Napoleon Bonaparte and an Habsburg army led by General der Kavallerie Michael von Melas. With Napoleon's army lying across the Habsburg army's line of communications to the west, Melas resolved to attack. Early in the morning, the Habsburg army advanced from the city of Alessandria and took the French army by surprise. It was not until 9:00 am before Melas' army completely moved through a bottleneck at the Bormida River bridges. At first the Austrian attack stalled, slowed by bitter French resistance. By 3:00 pm, the Habsburg army compelled their outnumbered opponents to retreat.^[1] Sore from having two horses killed under him, Melas handed over command of the pursuit to a subordinate and went to the rear.^[2] Later in the afternoon, a newly-arrived French division suddenly attacked the pursuing Austrians. Combined with a quick burst of cannon fire and a well-timed cavalry charge, the surprise assault caused a complete collapse of the Austrian center column, which fled to the temporary safety of Alessandria.^[3] The French suffered at least 7,700 casualties, including two generals killed and five wounded. The Austrians admitted losing 9,416 killed, wounded and missing, but some estimates range as high as 11,000–12,000 casualties. The Austrians lost one general killed and five wounded.^[4] The next day, Melas requested an armistice. The victory gave Bonaparte enough bargaining leverage to gain control of northwest Italy during the subsequent negotiations.^[3]
