Training areas
It was all very well to have the troops in Devon, but they needed to be prepared for the combat that was yet to come.
The fields and lanes of Devon became mock battlefields, and more than a few American soldiers learned to truly hate Dartmoor with its clinging damp, peat bogs, tors and tussocks that just seemed to go on forever.
In addition, to toughening bodies the techniques of infantry assault on an enemy held coast would have to be learned and perfected. Thus, in April 1943 a broad section of the coast of North Devon had been taken over by the US Army to create an Assault Training Center.
From Morte Hoe to Braunton Burrows a succession of American units learned the techniques of beach assault including the use of bazookas and demolition charges against pillboxes, the clearance of mines and the use of mortars against defences inland.
Essential amphibious practices were learned and rehearsed including landing on beaches in invasion craft, driving through surf in vehicles, and the delivery of invasion stores across a beach once it had been secured.
There were new techniques designed to cut a path through the obstacles and defences on well-defended beaches, and the level of co-operation between ship and shore, between different units, in the chaos of an assault landing, required careful training and then practice, practice, practice.
Larger rehearsals required more space than was available at the Assault Training Center in North Devon, so in late 1943 part of the South Devon coast around Slapton and Blackpool Sands, together with a hinterland including several small villages (just some 30,000 acres and 3,000 people), was cleared as a beach landing rehearsal area.
Facing out across Lyme Bay, Slapton would see a range of landing exercises growing in complexity and extent for units of the American Army, and the Anglo-American naval units whose job it was to get them ashore. One of those rehearsals (Exercise Tiger) would meet with disaster in April 1944 when a convoy of tank landing ships was attacked by German motor torpedo boats with the loss of 749 lives.
