" Greater cause for insomnia lay in not knowing the proficiency of one’s crew. Admiral Ghormley had been hampered by this uncertainty. He didn’t know what his ships and commanders were capable of. He hadn’t spent time with them, or among them; hadn’t been physically present to assess critical variables, from their intangible esprit to the physical soundness of their machinery. He was candid about this. “I did not know, from actual contact, the ability of the officers, nor the material condition of the ships nor their readiness for battle, nor did I know their degree of training for warfare such as was soon to develop in this area. Improvement was acquired while carrying out combat missions,” he would write. This was a startling admission of a leadership failure. "
