Based West Mersea Essex 2x4.7 inch guns in encasements with search lights. 1940-1942 Located on Victoria Esplanade. I am seeking to expand on the history of the battery. It seems to be named after 373 Field Bty based in Colchester in 1915 later going to Gallipoli. Was this related to Operation Fortitude ? In 1942 373 Bty emerged at Bulford under its previous designation which from memory was the Somerset or Dorset Yeomanry going on to Normandy 1944. I transcribed letters by Noel Beadle who began his TA service at 373 Bty was sent to OCTU at Bulford then transferred to Catterick where he went to 67 Field Regiment at Fakenham. Excerpts and details ref 373 Bty are found on the Mersea Island Museum website. Mersea Island Museum - a look into history He writes of a football match representing 10 Group Coastal Artillery and receives phone calls from HQ at Clacton. I cannot find much more as the battery seems never to have been.
