‘Exercise “Roundabout” was mounted at the port of Leith, near Edinburgh and consisted of ten phases, starting in mid-December 1943 and finishing in April 1944. In each phase eight or ten coasters carried mixed stores from Leith to Gullane, 20 miles east along the Firth of Forth. Gullane was the location of the Beach Group Practise Camp and at the beaches there the stores were off-loaded onto DUKWs, barges or landing craft, or discharged directly from beached coasters. The stores were then transported back to Leith by road (hence the name “Roundabout”, one presumes). The Exercise provided important training for Movement Control personnel and the Sea Transport Service in short sea voyage procedure. It also provided valuable practice for docks operating personnel in the loading and stowing of mixed stores, and for Beach Groups in the rapid unloading of stores on to beaches, day and night, in all weathers.’
