Logistics commanders who had sustained and attacked fleets

William Callaghan served as Nimitz's logistics chief before becoming the first commander of the Military Sea Transportation Service. Mercogliano contrasts his logistical ability with his brother Daniel's performance on the South Pacific staff, assigning Daniel responsibility for inadequate carrier fuelling before Guadalcanal. He also identifies submarine commanders Glenn Donaho and Lawson Ramage as effective later leaders of military sealift. Ramage explained his understanding of supply weaknesses through his wartime experience attacking Japanese shipping. The examples connect command of a support system with knowledge gained by operating it or disrupting an opponent's.
