Recon report-Casablanca Nov1942
 

There are several troop transports and numerous LCTs. When I first got there, a day after the place went pro-Allied, there was a Bogue aircraft carrier,
American destroyers are numerous BUT there are several sub nets and they can be tempted to crash onto it. The net does have a large opening to the SW of Casablanca. The water is clear enough you can see the netting through the periscope.
Allied air cover consists of pairs of Avengers and the occasional Hudson

Sounds like a nasty place to be, I'll be sure to steer clear.
