I’m a fan of Jack Coggins. An author and illustrator, Coggins has captured some golden nuggets of information in his book, Arms and Equipment of the Civil War. He has also written and illustrated a number of other mlitary history books no doubt influenced by his tour of duty as illustrator for YANK magazine during World War II. Members of Coggins extended family have put up a website (quite well done) by way of tribute to Jack. You can reach it here.
