Episode four of the Smithsonian Channel’s series Hell Below, entitled “Atlantic Showdown,” suggests a great scene of conflict in the Second World War. Yes, what is presented is symbolic of the efforts on the seas – but yet it is only a partial presentation of the full Allied effort.
Of all the theatres of operation during the Second World War, the Atlantic Ocean was one of the largest, stretching from the Arctic to South America, as ships of all shapes and sizes carried material such as bauxite from Jamaica, oil from Venezuela, and wheat from Canada, finished goods produced in the United States and Canada, as well as raw manpower from the New World to England. These efforts would be undertaken by a series of convoys (both slow and fast) departing from major eastern North American ports (New York, Boston, Halifax, Nova Scotia and St John’s, Newfoundland), under the escort of vessels of the Royal Canadian Navy, or when available, the Royal Navy or the United States Navy.
Sounds easy enough, especially since aircraft should be able to provide supporting cover. Ah yes. Unfortunately, there was a phenomenon called the Air Gap, which covered a great span of the ocean, over which coastal patrol aircraft from neither Canada nor Great Britain could reach. Welcome to the challenges of 1942 and early 1943.
In this episode, convoys HX-229 (a fast convoy departing from Halifax) and SC-122 (a slow convoy) – totalling over 100 merchant ships with just five escort vessels – cross paths in the Atlantic Ocean where they are intercepted by not one, not two, but three different Unterseebooten (U-Boat) wolf packs – in total, close to 40 submarines.
The episode very nicely explores the challenges of the Allied forces, addressing the limited number of support vessels for the convoys, and the challenges of weather and space. Equally, the Germany forces, lacking both distant and deep-seawater ports, were unable to replenish their vessels, resulting in a prolonged time at sea with a limited time of maximum capability – once they were out of torpedos, their offensive capability was limited to being an observation post.
What I liked most about this episode was the roster of the historical speakers who were featured. Now, I will admit a bias – I have known Marc Milner, one of Canada’s top naval historians, for years, so it was thrilling to see him speak. Equally, the input of the British and German speakers (notably Fregattenkapitän Christian Jentzsch) gave the episode context. This wasn’t just a one-sided depiction of the events, nor was it a one-sided battle: each side was at risk – and each side has something to talk about in terms of successes and lessons learned.
As a student of history in the 1990s, I had the fortune to be at a university with both a strong military history program, as well as a strong naval history program. One of the key lessons I remember – and which is glossed over in this episode (albeit perhaps indirectly) – is that, during the Second World War, the Royal Canadian Navy grew from an undistinguishable small fleet to one of the largest in the world. Our role in the convoys and the Atlantic theatre – both in terms of the merchant navy, who for many years had been (at least within a Canadian context) a forgotten component of the convoys, and the RCN itself – is worth recognition. It should also be remembered that, as the war progressed, Canada was the only Allied naval force with assets in the Atlantic able to respond to an effort to support the convoys – the result of British and American assets being drawn from the Atlantic to support efforts elsewhere. This tenuous situation became compounded in late 1942 when the British requested that convoys shorten their travel times, in an effort to bring more materials to the United Kingdom which was facing a continuing shortage of goods. 1 Perhaps it is an appropriate afterthought to note that, during the Second World War, the only Canadian to achieve Command of a theatre of operation was Rear-Admiral Leonard Murray, Commander-in-Chief Canadian Northwest Atlantic, beginning in April 1943. As a result, the Royal Canadian Navy assumed “the acknowledged role as guardian of the convoys.” 2
