Ancient Mariner
You're right in what you say about the Merchant Navy but if you ever get to the Scottish National War Memorial in Edinburgh Castle, you will see panels paying tribute to Merchant Seamen, Nurses, Miners and even animals like pit ponies, carrier pigeons and rats, mice and cagebirds that were used to detect gas.
Below The Castle, in West Princes Street Gardens is the Scottish American War Memorial and my father, who always turned out proudly with The Navy Club for the Service of Remembrance at The City Chambers, then joined the men of The British Legion, Scotland for a second Service down there. Maybe their names are not shown but they are not fotgotten!
