I came across this picture on the internet. There's no caption or any kind of explanation. What is happening in this picture? The U boat seems to be signaling the UK warship, the warship is obiviously not feeling threatened. Smoke seems to be billowing out of the U boat's conning tower, are they signaling for help??? If so, this would have to be prior to the outbreak of hostilities. Great picture, I just wish I knew what was happening.
