Each man was capable of independent action.
They all knew the folly of throwing away a single shot.

There was no random firing.

Each man was trained to seek sure protection behind rock, stump or tree, and then to keep a vigilant watch, not only to guard himself but his immediate comrades from the missiles of the foe.

Slowly the line of trappers was to advance upon the enemy, from point to point of protection, making sure that every bullet should kill or wound.

The tactics of the battle secured the victory.
