yes, in SH V on the Churchill Express scenario-sinking 5 transports, even using French port Dakar to refuel enroute to ambush sites at Freetown or even further at Capetown (where the ships are sitting ducks at anchor) on the African coast, meticulous alternation 'twixt recharging on the surface at a fuel conserving pace and slow but complete battery consumption at scope depth are necessary to regain the French coast port of St Nazaire.
