In late May 1942, Japanese Admiral Isoroku Yamamoto sent four aircraft carriers to attack the Pacific Fleet facilities of Midway Island.  Yamamoto expected the Pacific Fleet carriers to rush to the scene from Pearl Harbor and into the trap he had prepared.

However, Admiral Chester Nimitz had built a brilliant cryptography team at Pearl Harbor, and they informed him of the coming carrier attack.  Nimitz planned a surprise ambush of the Japanese carriers.

Nimitz had three carriers, Enterprise, Hornet and Yorktown, each with a squadron of fighters and torpedo planes and two squadrons of dive bombers – a total of over 230 planes.  Nimitz quickly assembled a mixed bag of over seventy Navy, Army and Marine Corps planes on Midway Island.

The Nimitz ambush called for planes from both Midway and the carriers to arrive simultaneously over the Japanese carrier fleet in a concentration of force and deliver a devastating attack.

LtCdr Edwin T. Layton, Pacific Fleet intelligence officer, predicted on May 27 that the Japanese fleet would approach from the northwest, steam toward Midway on a southeast course of 135 degrees, and launch an air attack on Midway Island at 0430 on June 4.[i]  The Nimitz plan called for PBY scouts to fly from Midway at 0430, contact the Japanese carriers about 0600, and report their position, course and speed.

Upon receiving the PBY report, the attack planes from Midway would fly the reverse of the Japanese course and intercept the Japanese carriers 140 miles from Midway at about 0720.

To establish the position of the carriers, Layton would have drawn a line from the interception point to the northeast, perpendicular to the Japanese course, and would have marked a point on the perpendicular line 140 miles from the interception point.  The carriers were to be at that position at 0600.  Upon receipt of the PBY contact report, they would fly 140 miles to the interception point, well within their 175-mile maximum operating range, and meet the Midway planes over the Japanese carriers at 0720.  The starting position for the carrier launch also measured 200 miles straight north of Midway Island and would be used as the navigation reference point by the carrier command.[ii]

The carriers departed Pearl Harbor and were northeast of Midway by June 2.  Rear Admiral Frank Jack Fletcher was in overall tactical command.  At 0430 on June 4, the PBY search planes from Midway flew on their assigned vectors.  At 0603 a PBY reported contact.  On receipt of the PBY report, every flyable plane on Midway took to the skies.

However, at 0600 the Pacific Fleet carriers were over sixty miles to the east and north of the position 200 miles north of Midway.  They also were about 200 miles from the interception point with the Japanese carriers, and the planes were out of range.  The distance would have to be shortened by at least 25 miles to get to maximum operating range.  At the carrier speed of 25 knots, that would take an hour.  The launch time was reset for 0700.

The plan for achieving a concentration of force of carrier planes and Midway planes over the Japanese carrier fleet had failed.  The Midway planes arrived alone over the Japanese carriers at 0710 without fighter protection, and Zero fighters shot down most of them.  No hits were scored.  The carrier planes, 175 miles away, began launching at 0700.

Starting about 0920, Hornet and Enterprise torpedo squadrons found the Japanese carriers and began gallant but hopeless attacks.  Another hour after that, at 1020, a massive Japanese counterattack was nearly ready to attack the Pacific Fleet carriers that could have resulted in a Japanese victory.  However, at 1025, Dauntless dive bombers from Enterprise and Yorktown arrived and destroyed three of the four carriers.  The fourth carrier was destroyed later in the day, but not before its attack on Yorktown led to the loss of that carrier.  With four enemy carriers sunk, Midway would go down as the greatest naval victory of the Pacific War.

The Nimitz concentration of force attack plan was the best chance to achieve an early victory at Midway with a high probability of success at the least cost, but the plan failed when the carriers were out of position at the appointed time.

  1. I have always thought that it was not pure luck the Dauntless dive bombers happened to be there just in nick of time.
    What happened was that there was a plan to know when exactly that time period was for when the Japanese fighter planes absolutely had to return to their carriers and re-arm and refuel and that is when to attack with dive bombers.
    So this time period of refueling and rearming was cleverly “forced” by the USA, and the carriers were sunk because they had no air-cover when the dive bombers showed up, plus the decks of the carriers filled with munitions and fuel too so just one direct hit could blow the carriers sky high.
    First they sent in the Midway land-based planes, as the Japanese did not know that the US carriers were close, so the USA did not use carrier based planed on purpose to fool Japanese.
    After this, the Japanese launched an attack on Midway island itself after this attack… All the Japanese planes set up for land-based attack. But then when they returned, they had to switch all their ordinance in panic on the decks of the carriers since now they knew they were in trouble, and carrier based planes were coming in.
    And it is this time-slot that the dive bombers showed up.
    The failed torpedo bomber attack was a sacrifice, to make sure the fighters were in air to shoot them all down, and when they also returned to refuel and re arm, thats when the dive bombers hit. It was all planned.

  2. I had the good fortune of an Admiral Worthington ret. for a substitute teacher in Civics class, 8th grade. Sometimes we had a boring film but at times he would talk about Midway. Facinating history .
