Finally - after 18 months!
Late November 1943 - 23rd patrol in my third career - in my type VIIC hunting Murmansk convoys well north of Trondheim. After several days of seeing nothing at all, I decided on a lark to pop up to the bridge one afternoon and scan the horizon with my binoculars, when I spotted a dark shape at long range off my port quarter. Altering course to investigate, I finally saw one - - ICEBERG, RIGHT AHEAD!
