16:15 Passing the destroyer on bearing 270. I can now clearly see the masts from the convoy on front of it.
16:52 Periscope depth, turned towards the convoy, filled tubes for underwater attack. Strangely, I find myself in exactly the same position as our last attack. Might not be the best idea, but no time to change position.
