I came across this article from Time Magazine in early 1943 (dated 12/28/42) concerning convoy protection. I think it's worth a read.
"Last week's compilation of ship sinkings showed that from Jan. 1, 1942 to Oct. 1, 490 Allied ships had been sunk in the western and south Atlantic by Axis submarines; from Oct. 1 to Dec. 20 only 65 more. This notable success in the Battle of the Atlantic was not gained in any single thrilling action. The following account of the labors of a U.S. convoy vessel (given with a fictitious name) tells something of how that success has been won:"

Not a bad article Lou. From the merchant Marine Vets I've spoke with, many claim they owe everything to the tin cans doing the escort duty. A less publicised but no less worthy task.
