. Mentally, he had become a cautious officer who worked hard going over tactical plans of every operation he was involved in.

Admiral Nishizo Tsukahara had some doubts with his appointment, and commented, "Nagumo was an officer of the old school, a specialist of torpedo and surface maneuvers.... He did not have any idea of the capability and potential of naval aviation." At home, Nagumo did not receive a loving description, either. One of his two sons described him as a brooding father who was obsessed (and later disappointed) with pressuring his sons to follow his footsteps into the navy. Contrastingly, Nagumo's junior officers in the navy viewed him as precisely the father figure his sons did not.

However, despite his lack of experience, he was a strong advocate of combining sea and air power. Nevertheless, he was opposed to Admiral Isoroku Yamamoto

, Nagumo′s personal score card saw five battleships, one carrier, two cruisers, seven destroyers, dozens of merchantmen, transports, and various other vessels. He was also responsible for downing hundreds of Allied aircraft from six nations. Destruction brought upon Allied ports also disabled or slowed Allied operations. All the while, he had lost no more than a few dozen pilots.

However, at the Battle of Midway

The Battle of Midway is widely regarded as the most important naval battle of the Pacific Campaign of World War II.

, and the massive losses of carrier aircraft maintinence personnel would prove decisive to the performance of the Japanese navy in later engagements. Although 110 carrier aircrewmen were lost during the battle, their loss was not as cataclismic as the loss of the four carriers, their aircraft, and the men responsible for their maintinence.
