By July 1757, in the aftermath of defeat at Kolin, the situation looked bleak for Frederick the Great of Prussia. French troops had invaded allied territory, whilst other French and Austrian armies were moving towards Hanover. Marching west, Frederick's men faced French and Austrian troops at Rossbach on 5 November. In less than two hours it was over. The Allies had lost 10150 men and the rest fled. This title examines how on 6 December, Frederick won what was perhaps his greatest victory at Leuthen. More than 12000 Austrians were captured, and 6750 killed. Five days later, Breslau surrendered. Napoleon referred to this campaign as a "masterpiece of manoeuvre and resolution".
