It's the Royals, or the Enniskillens, or the Household.

You can hear their cymbals and kettles.
The French heavies are too good for us.

They have ten to our one, and good men too.

You've got to shoot at their faces or else at their horses.

Mind you that when you see them coming, or else you'll find a four-foot sword stuck through your liver to teach you better.
