Hi
One small gaff not mentioned in the in the main thems happens very early in the picture when the Lydia anchors in the bay. As Bush and Hornblower await the boat carrying the natives Bush comments "A rum lot sir" to which Hornblower replies "They are our allies Mr Bush".
Later when Hornblower is in El Supremo's palace and is giving a list of provisions he will need he asks the aide if there is any wine to be had. The aide replies, "We have a spirit made from molasses that you won't of heard of we call it rum".
Regards
