I served my apprenticeship in Falmouth Docks between 1962 and 1967 and worked with quite a number of ex RN and Merchant Navy men who had served right through WWII. Having a keen interest in the sea and ships, I went to work in the docks as it was the only way at the time I could get into the Merchant Navy as an officer, a lot of them would talk to me about their experiences as they understood I had a very genuine interest in what they had done. And what they did, above all others, was to save this country from defeat.
For once the programme gave a reasonable feel for what it was like, although the escort provided for the Arctic convoys was vastly better than that provided for the North Atlantic convoys between 1939 and the latter part of 1942. In 1940/41 the average escort for a 60 ship convoy normally consisted of one old destroyer and three or four corvettes, which would try to defend them against a wolf pack of between four and eight U-Boats.
The men of the Merchant Navy have never been given the recognition they deserve for their bravery. Although they had a higher proportion of manpower losses to numbers engaged, approximately 30,000 out of just over 300,000, than any of the armed services, they were not under military discipline or any form of duress to sail, but were all volunteers and no ship ever failed to sail for want of a crew. I think the problem was that they didn't have smart uniforms, brass bands and shiny equipment to show off, but wore nondescript clothes, sailed equally nondescript merchant ships and died in the open sea, out of sight and out of mind.
In 1940 everybody could see the fighters in the Battle of Britain, but very few people realised at the time, and even less now, that without the men of the Merchant Navy the planes would never have got off the ground for lack of fuel, as nearly all the petrol they used was imported from the US Gulf. It must have taken a very special sort of bravery to sail a ship loaded with 12,000 tons of aviation spirit thorough waters containing U-Boats, not just for a few hours but day after day, knowing that a torpedo hit meant an enormous explosion and death, for voyage after voyage.
