One of the canon experts told me he had a farm called Kanonkop not far from where wee lived in Cape Town's Durbanville suburb and he had something I might be interested in. It turned out to be an old cannon, made in Falkirk and sent out with the Argyll and Sutherland Highlanders when Napoleon was causing all the trouble. The Brits took over the colony to prevent it being used to threaten the route to India. The general in charge was a Scot called Baird, who fought two 'battles' in which there were a few sprained ankles and red faces but at least one of his canon is preserved at Kanonkop. The canon was cast at Falkirk in the Carron works and bears King George's insignia of the time.
