When I contacted Mr. Engler about submitting a little information about his time aboard the U.S.S.
Cavalla during World War II, I had no idea the man possessed a war time photography collection
that daunts the Smithsonian. Here are historical treasures that have no peer on the Internet. Although
photography in the 1940s doesn't match today's standards, these photos possess a captivating quality
all of their own. Enjoy!
