After-action report
The after-action report of Rear Admiral Frank Jack Fletcher confirms the intended movements of the carrier force in conformity with the Nimitz plan:
ENTERPRISE and HORNET maintained their air groups
In readiness as a striking force. During the night of June 3-4
both forces [TF-17 and TF-16] proceeded for a point two
hundred miles North of Midway. (Emphasis added) Reports of enemy forces to the Westward of Midway were received from Midway and Commander-in-Chief, Pacific Fleet. These reports indicated the location of the enemy Occupation Force but not the Striking Force.(2)
The ComCruPac (Fletcher) report refers to PBY scouts on June 3, when the Occupation Force was sighted and the carrier Striking Force was still under heavy clouds. It confirms Fletcher’s knowledge of the plan and his intended movements. Further confirmation of the Nimitz plan and the ordered position of the carriers to be 200 miles north of Midway at 0600 on June 4 is contained in published accounts of at least three contemporary historians who had the opportunity to interview participants during and after the war: Richard W. Bates, Samuel Eliot Morison, and E. B. Potter. (3)
On June 3 the PBYs took off from Midway at 0430 and contacted the Japanese occupation force. This contact confirmed that the Japanese were proceeding with the plan as previously decrypted by Layton’s intelligence unit. The carrier force was still under a heavy weather overcast and was not discovered on June 3.
On June 4 the PBYs launched again at 0430. At 0534 a sighting of enemy carriers was transmitted to Admirals Fletcher and Spruance, and to the forces on Midway. At 0603 the earlier report was amplified:
“2 carriers and battleships bearing 320 degrees, distance 180, course 135, speed 25 knots.” (4)
Immediately after receiving the latter report the planes on Midway took to the air. Fighters rose to defend Midway, and six Avenger torpedo planes and four B-26s fitted with torpedoes flew to attack the Japanese carriers. Two more carriers were in the Japanese formation but were not seen by the PBY pilot.
However, Pacific Fleet carriers were not in position to launch planes at 0603 because Fletcher, while heading southwest overnight June 3-4 toward the designated position 200 miles north of Midway, decided that the scouting as ordered in Operation Order 29-42 might not be sufficient. At first light, he ordered Yorktown carrier planes to conduct a separate sweep to the north and east. To do this the carriers had to change course to the southeast to launch planes into the wind, and to be on that course to recover the planes. These course changes took the carriers away from the interception point. When the 0603 message from the scout arrived, the carriers were 200 miles east and north of the interception point and 25 miles beyond their operating range of 175 miles.
At 0607 Fletcher sent a message to Spruance:
“Proceed southwesterly and attack enemy carriers when definitely located. I will follow as soon as planes recovered.”(5)
Spruance, detached with Enterprise and Hornet, proceeded southwest at all possible speed to close the range, but at an average speed of 25 knots it would take an hour to cover 25 miles. Meanwhile, the planes from Midway arrived separately over the Japanese carriers and attacked. The plan for a concentration of force had failed.
The Avengers and B-26s, arriving at 0710, flew into the teeth of the Zero fighter defenders. They attempted valiant torpedo runs against two of the four carriers, but the inexperienced pilots were hopelessly outclassed by the fast, agile and deadly Zeros. There were no hits or even good chances for hits, and the Zeros sent five of the six Avengers flaming into the ocean. The B-26s hardly did better, but one pilot, with his plane on fire and probably knowing he was never getting home, dove at the bridge of the Japanese flagship. He missed by a few feet and crashed into the ocean.
B-26 pilot
The B-26 pilot may have done as much as anyone that day to turn the tide of the battle. At 0715 the shocked Admiral Nagumo, already notified that the Midway attack had run into heavy resistance, decided that a second attack on Midway was required. He ordered the armaments of the standby force to be changed from anti-ship bombs and torpedoes to point detonating bombs for land targets. All of this would require over an hour to complete, and not before the Midway attack force would be returning to land about 0830, low on fuel.
Admiral Spruance, ready to launch planes from his two carriers at 0700, plotted courses to a new interception. Ranging closely together between 231 degrees and 240 degrees, but delayed at the launch, the planes expected to arrive at the new interception at 0925 – almost 2 1/2 hours after the launch time.
At 0917, with the Midway force landed, Admiral Nagumo turned northeast to confront the Pacific Fleet carriers that a Japanese scout had discovered earlier. Decisions he had made, including landing the Midway planes, had delayed any attack on the American carriers. The Americans were still making attacks, but the Zeros swept them aside easily. Now Nagumo was supremely confident. Rearming and refueling the entire air complement on all four carriers would be completed by 1045. They would launch a massive, coordinated attack of over 200 planes and sink the American carrier fleet.
The Enterprise and Hornet planes crossed the revised intercept point at 0925 but found nothing but open ocean. The Hornet air group commander took his squadrons southeast to protect Midway. The Enterprise air commander realized that the Japanese carrier force probably had been delayed by earlier actions. He took two squadrons of dive bombers on a northwest course to retrace the Japanese movements, then began a box search that came upon a Japanese destroyer, and that led to the Japanese carriers. Diving out of the sun at 1025 caught the Japanese defenders by surprise, and in five minutes Akagi and Kaga were destroyed. The Yorktown planes suddenly appeared and destroyed Soryu.
Hiryu, the remaining Japanese carrier, launched dive bomber and torpedo plane attacks which led to the loss of Yorktown. Later in the day on June 4 Enterprise dive bombers destroyed Hiryu. The greatest victory of the US Navy had been realized.
Aftermath
In the aftermath of the Midway victory no one was going to complain about not following the Nimitz battle plan, least of all Admiral Nimitz. Consequently, the existence of the plan has been overlooked until now. Whether following the plan would have resulted in the same victory by Pacific Fleet forces, or the same victory without as many losses in ships, planes and personnel, has never been explored and is left to speculation.
