Until the widespread introduction of the Sten gun into British service, the Thompson was the prominent sub machine gun used in the British Empire, with nearly half a million being supplied to the British government form the US. The story of this British procurement is often wrapped up in rumour and anecdote rather than fact- for instance according to popular legend most of the guns ended up at the bottom of the Atlantic Ocean after the ships carrying them were sunk by U-Boats. Up until now most histories of the Thompson machine gun have concentrated on the development and manufacture of the weapon and its extensive US service. British sales have often been relegated to a few paragraphs.‘Great Britain- The Tommy Gun Story’ by Brian Davis Jnr seeks to address this gap by looking at the specific purchases of guns by the British, both under the Cash and Carry scheme and under Lend Lease. Davis has gone back to the original documents and telegrams sent by the Ministry of Supply in Great Britain and he looks at each order in turn, how many guns were purchased, what spares and magazines were supplied with them and how the MoS tabulated them. From all this it seems that we finally have an accurate figure for the number of weapons acquired, rather than the guesses put forward by previous authors. Equally important is his analysis of the ships transporting the weapons and how many of these were actually sunk. By looking at the figures he comes to the conclusion that only around 4% of the weapons sent across the Atlantic actually failed to complete the journey due to enemy action. I must confess this figure was far lower than I had already assumed and shows the importance of actually looking at the original documents rather than relying on anecdote!This book is very much a history of procurement, rather than the service use of the Thompson by the British and as such does not have any information on the British combat use of the weapon. As mentioned it does not cover the development history of the weapon either, however other books have already covered this topic and this is a niche publication that sets out to look at how Thompsons were procured, how many were purchased and how these orders were fulfilled. As such this book may not appeal to every reader, however for those with a specialist interest in British small arms of the Second World War this is an invaluable volume and helps clear up several myths once and for all. One area of particular praise is the number of original documents that are reproduced in the book, either as transcripts or as copies of the originals. Primary source based history is always to be commended and it is clear the authors spent many hours going through archives to find this information.The book is a print on demand paperback title from Amazon and as such normally takes a few days for delivery. This is the first print on demand book I have purchased and I was pleasantly surprised by the quality of the printing and binding and this sort of esoteric title is ideally suited for this medium as it allows it to be available on a continuous basis despite the presumably limited sales it would generate. The book can be found here.
