I always thought the "hireling and slave" reference was to the British army. I've heard other references to the subjects of kings being slaves. The current national anthem of Ireland refers to English people as slaves.
I suppose it is possible that Key was referring to runaway slaves who had joined the British army.

The colonial marines who were escaped slaves did participate in the battle he was writing about, so why wouldn't it be seen as glorifying in the deaths of the escaped slaves?
