9.2 inch Howitzer Mk 2

The numbers in service in 1939 were few and some of these were left behind in France. It was obviously useless in modern, mobile war taking 12 hours to bring in to action. So they were emplaced on the south east coast as anti-invasion defences. It was not declared obsolete until August 1945 although there is little evidence of it being used, even for training after mid 1942.
