Surrender of Sérurier's division at Verderio

On the early morning of 28 April an advance detachment of one Austrian battalion under Louis Victor Meriadec de Rohan-Guéméné and the Pozdneev Cossack regiment met a cavalry post on the hill behind Imbersago; the Cossacks, advancing toward Paderno, overturned the post and unexpectedly saw a whole French detachment. The French defended stubbornly at Verderio and even unsuccessfully attempted a flank attack, repelling unsupported hussars, but ran out of ammunition. An Austrian attack in several columns—a favourite tactic since 1758—by superior numbers, together with the approach of Rosenberg's main Russian troops, about 17,000 Coalition forces, convinced Sérurier that further resistance would be reckless, and he surrendered.
