the french man started to walk around the forest, doing the usual patrol on the forest that he always did, to stop the British army from entering the territory

He stopped Next to a lake, getting down from his Horse while singing something in french, he was usually singing a little when he reach the lake since that zone was safe enough and no one would cause and ambush there Right?

Aparently he wasn't right since he heared something behind him, in some bushes and trees behind...
