yes, it does happen like that too.. when your all but sure.
The worst one for me anyways happens if I have recently used the deck gun and the men manning it are still able to fire at will. You know that they are so hungry for the tonnage that they will fire on any neutral ships, when they are in range and of their own accord. Imagine the suprise when I had identified the ship as a neutral and then hearing the first round fire. I thought I was under attack, with no officer on watch...I pushed him up top and then joined him. I think they were on the third round by then, when I realized that the boat I was going to let pass... was on fire.
