The battle of Rosbach(*) is another example, if we suppose the commander of the allied army had not really the intention of attacking Frederick the Great.
Of the battle of Soor,(*) the King himself says that it was only fought because a retreat in the presence of the enemy appeared to him a critical operation; at the same time the King has also given other reasons for the battle.
On the whole, regular night surprises excepted, such cases will always be of rare occurrence, and those in which an enemy is compelled to fight by being practically surrounded, will happen mostly to single corps only, like Mortier’s at Dürrenstein 1809, and Vandamme at Kulm, 1813.
