72 • THE ROAD TO VICTORY: From Pearl Harbor to Okinawa
THE US PLAN
Despite popular myth, Nimitz's decision to
engage the Japanese at Midway was not a
desperate gamble against impossible odds but a
carefully calculated plan with great potential to
cause serious damage to the enemy. Good
intelligence played a part. The Pacific Fleet's
cryptologists had assembled a fairly close idea of
the IJN's intentions. The main target of the
operation was identified as Midway, where four
to five large carriers, two to four fast battleships,
seven to nine heavy cruisers, escorted by a
commensurate number of destroyers, up to
24 submarines, and a landing force could be
expected. Additional forces, including carriers,
would be dedicated against the Aleutians. The
operation would be conducted during the first
week of June, but the precise timing remained
unclear. All in all, this was a fairly close
approximation to Japanese plans, but somewhat
lacking in specifics.
To engage the Japanese, Nimitz carefully
arrayed his available assets. Unfortunately for
Yamamoto, his plans were nothing like what
the Japanese assumed. Despite the constant
suggestions from US Navy commander Admiral
King that they be employed as aggressively as
possible, Nimitz immediately decided that
there was no place for the Pacific Fleet's seven
remaining battleships. He did not want his
carriers to be hamstrung in any way by the
slow battleships and he had no assets available
to provide them with adequate air cover or
screening. The battleships remained out of
harm's way in San Francisco.
The Pacific Fleet's striking power resided
in its carriers. Two of these, Enterprise and
Hornet, were assigned to Spruance as TF-16
and would be off Midway by June 1. The
damaged Yorktown, still in TF-17, remained as
Fletcher's flagship and would be in position
off Midway by June 2. Fletcher would assume
overall command of the two carrier groups
when he arrived.
Nimitz held a major advantage in that the
battle was being fought within range of
friendly aircraft. Midway was jammed with as
many aircraft as possible, including a large
number of long-range reconnaissance aircraft,
fighters to defend the base from air attack, and
a mixed strike force of Marine, Navy, and Army
Air Corps aircraft. Defending the base were a
number of submarines and a garrison of some
2,000 Marines.
Employment of Midway's 115 aircraft was
an important consideration, in particular the
long-range PBY flying boats which were able
to conduct wide-ranging searches, greatly
reducing the possibility of a surprise air raid on
the island. Nimitz agreed with his staff that the
best position for the carriers was northeast of
Midway. By being fairly close to Midway, they
could respond quickly to attacking enemy
carriers. Most important was the question of
risk to the carriers. Nimitz never saw the battle
as a death-struggle for control of Midway. His
orders to Fletcher and Spruance provided the
guidance that they were to "be governed by the
principle of calculated risk which you shall
interpret to mean the avoidance of exposure of
your forces to attack by superior enemy forces
without good prospect of inflicting, as a result
of such exposure, greater damage to the
enemy." On top of these written orders, Nimitz
personally instructed Spruance not to lose his
carriers. If required, he was to abandon Midway
and let the Japanese attempt a landing. Even if
captured, it could be recaptured later. It must
be assumed that Nimitz provided the same
instruction to Fletcher.
Finally, Nimitz believed that the IJN
carriers would be operated in two separate
