The task of rehabilitating the Brittany ports of Cancale, Saint-Brieuc and Saint-Malo was carried out by the 1053rd Port Construction and Repair Group and the 360th Engineer General Service Regiment, but work on Saint-Malo was abandoned as it neared completion because the task of opening the inland waterways serving it was not considered worth the effort. It was handed over to the French on 21 November. Tidal conditions at Cancale proved unfavorable, and it was never used. Saint-Brieuc was opened in mid-September but discharges averaged only per day, mostly coal for local railways and power stations, and it was handed over to the French on 9 November.
