Query

[callmemadam]

Call me a boring old pedant, but. I've been constantly irritated in a book I'm reading by references to 'cannons'. Now I've just seen the same usage on the BBC news website in connection with the Waterloo commemorations. Isn't the plural of cannon, cannon? As in
Cannon to right of them,
Cannon to left of them, etc.?

If I'm wrong, I take it back.
