Hello, I need help with the shots made by the English heavy batteries in the Dover sector against the German batteries in the Gris-Nez and Calais sectors in september 1944. I have a lot of information but some seem contradictory. In particular, regarding the day of September 20: did Wanstone's 15 inch guns fire? How many shells were fired by the 14 inches guns of St Margaret ? Colonel Maurice-Jones in "History of coastal artillery in British army" speaks of 85 shells for Wanstone and 198 for "Winnie" and "Pooh". This seems very high, especially since the excessive wear of the barrels, particularly for the 15 inch barrels, prevented them from reaching the French coast. Any help would be welcome ! Thanks in advance.
