On the Campaign

Captain O'Neill's Company on the right, is annihilated. He comes to the left of his regiment, where Lieutenant-Colonel Fowler and Major Bentley are:
"You must give me another command - not one of our Company remains able to do duty."
He had another command very soon. Lieutenant-Colonel Fowler and Major Bentley are wounded, and have to go to the rear. Captain O'Neill takes command of all that remains of the regiment. The right wing is completely gone, and only a portion of the left is still standing - the others have been either killed or wounded ...
