Built by Napier & Miller in Old Kilpatrick, the Eagle III was a paddle steamer launched in 1910 and originally owned by Buchanan Steamers.

In the First World War she was used as a minesweeper by Admiralty and in the Second World War took part in the Dunkirk evacuation as HMS Oriole. When interestingly she was deliberately ran aground by her skipper to allow men to board and the vessel to sail away when the tide came in again. See this article in the Herald and this personal recollection by Lt Lindsay who served on her as HMS Oriole.
