A day after defeating MacDonald at the Trebbia, the Allies captured the 17th Light Demi Brigade, 1,099 men, six guns and three colors. On 22 June Suvorov halted pursuit by his army, exhausted by continuous marching and fighting. At first a division was allowed to follow the French, but this was soon reduced to an Austrian advanced guard under Johann von Klenau which went on to clear the Grand Duchy of Tuscany of enemy forces. On 20 June, Moreau and 14,000 French troops left the security of the mountains to defeat Count Heinrich von Bellegarde and 11,000 Austrians in the Second Battle of Marengo. Bellegarde withdrew to the west after suffering 2,260 casualties but Moreau soon scampered back to the safety of the Apennines after hearing news of the Trebbia. French casualties numbered 1,000 killed and wounded in this encounter.
