KEY: How to
read numbers in lower left corner of 1st map.
Example: The map entry for Target 15 is as follows:
Target Grid # Barrels MM Type Range (yards)
15 342102 4 150 H 14600
Note: 1st Map shows Target 3 (St-Marcouf/Crisbecq) originally having six 155mm guns.
However, those guns were moved and three 210mm guns were installed at Target 3. The 210-mm guns had a range of 32,800 yards -- 18.5 miles -- and they fired on the
USS Corry at less than 3 miles -- virtually point-blank range.
