Sound officer a saboteur?

[Frin63]

This is weird. Have been cruisng the North Atlantic for days in search of enemy warship (Blockade of Germany, jan 1940). Seas seem completely empty. Every now and the we dive to listen around. Every time I take over the earphones myself and immediatley the whole crew starts wiping their feet and stamping around as loud as they can. After another hour of slow underwater cruis I ask the sound guy if he spots anything. "Yes, there is an enemy warship, about 8000 meters on the port site".

Now isn't it a logic thing that he would report something like that without my asking for it after days listening to empty seas??? Can I have this guys executed for treason???
