Horses; training. Horse Guards lined up; doing sword drill on horseback; in which they lunge forward; point swords up; down; etc Guards; now wearing long overcoats w/ bare legs sticking out(which makes them look like the classic dirty old men pervert in a raincoat) walk along leading horses. Riding horses into the Thames river -- the riders in old-fashioned swimsuits or shorts. Shots of horses swimming across - and at least 1 turning around.

MS a rowboat in the river; w/ the fallen guard swimming to it; and on other side another guard on a horse; w/man in uniform standing in boat holding rope tied to horse --3 other guys (in swimsuit; long shorts; and very brief shorts) standing up in the boat; rowing-- the whole scene looks like chaos. Pan along guards on horses; facing
