Foy's division was the only French unit not engaged in the battle, and it was acting as rearguard on 23 July.
Bock's 770-strong heavy cavalry brigade, consisting of the 1st and 2nd King's German Legion (KGL) Dragoons, led the pursuit of the French.
Their volley killed a number of horsemen, but a mortally wounded horse carrying a dead dragoon crashed into the square like a battering ram.
[4] The horse fell, kicking wildly, knocking down at least six men and creating a gap in the square.
The very high proportion of killed to wounded was due to the "deadly effect of musketry at the closest possible quarters.
"[7] Another authority gives 52 KGL soldiers killed, 69 wounded and 6 missing and 1,100 total French casualties.
