October 20, 1942 - Ax The Axis Patriotic Cover - Free Postage (USS Edison)

On 24 October 1942 Edison set sail from Norfolk with a task group bound for the invasion at Fedhala, French Morocco, 8 November. She engaged shore batteries and enemy destroyers at Cape Fedhala and protected shipping lying off the beachheads during the Naval Battle of Casablanca:

A total of 362 rounds were fired, 74 at the shore battery, 20 in the first engagement, and 268 in the second destroyer engagement, of which it is estimated that 200 rounds were fired at the first destroyer and 68 at the second. All firing was director-controlled, rapid, continuous fire. The average gun range for the first firing was 9,500 yards, for the second 14,000 yards, and for the third 12,500 yards ...

... It is particularly pleasing that the guns maintained a sustained rapid fire of 268 rounds (average 68 rounds per gun) at an estimated rate of at least 12 shots per gun per minute without casualty.
