I guess the Japanese escort sub detection levels are turned up pretty high?

I made early for Battle of Sunda Strait and was really pleased when the "convoy" comes along. I was lingering on the fringe, no engine on at all, 70 ft depth, silent running, no scope up. Just waiting on about 32 speed as the convoy pulled up. I had been submerged for an hour so I don't think they had spotted me before I submerged.

The enemy escort nearest to me just honed in like a blood hound.

It was still daylight (last couple hours of it) and it was shallow water, so I suppose there might have been a shadow or silhouette that was spotted.

Can active sonar discern a boat sitting nearly on the bottom in this era?

I don't know if he used any active or not, I was on 32 or 64 speed and didn't realize he was depth charging me till it paused down to 8 speed.
