Heh.
Actually I had been tooling right along at periscope depth for awhile at one point. However, having my Obs Periscope up didn't help against the air attacks as they zeroed right in on me.
The reason I started running on the surface was that my battery was down to about 1/4 after a few hours of that business and it was still mid-afternoon.
Note to self: Must travel at ahead slow while submerged due to battery life. This ain't Duracell.
