 However, as they arrived in the vicinity the Austrians found themselves caught between Masséna and Bonaparte's other divisions which operated against their rear.In the first clash on 21 March, Masséna's advance guard pushed General-major Joseph Ocskay von Ocsko's Austrians out of Tarvis, blocking the escape route.Later that day, General-major Charles Philippe Vinchant de Gontroeul appeared with another column and drove the French from Tarvis.
