Convoy Circles?

Has anyone else seen this?

Thanks.

The circle means that the convoy is being shadowed by an Uboot.
Close in and attack.
You might witness a wolfpack attack but the AI Ubooten will attack surfaced with their deck guns and thus they make themselves easy targets for the escorts. This is a blessing in discuise (spelling correct?) for you as you have planty of time to attack the merchants with your torps and escape.
