I dont think they left their bases together as a group of uboats, that wouldnt be very smart in case of attacks. When the wolfpack tactics was introduced several uboats were ordered to patrol more or less the same area. When one of them spotted a convoy a message was sent to the others, and those up to 10-12 hrs away at maximum speed rushed to the scene. The boat in contact with the convoy followed it until the others arrived, and then they planned an attack together. Each boat got its own target, and the planning was also important to avoid running in front of each others torpedoes.
