Tabulating casualties for naval battles is somewhat different from that for land
battles. For the latter, a convenient, first-order comparison is simply the numbers or the
percentage of human casualties, those killed, wounded, or missing, as stated above. If the
numbers are close for both sides, then other measures of the severity of casualties is
needed, such as destruction of better units or of a certain military arm—cavalry, for
example. For naval battles, however, one loses both ships and men, and possibly aircraft
depending on the battle. Losing 2,000 men from five ships still afloat is different from
losing 2,000 men on a single sunken battleship. For Midway, the number of personnel
lost, 300 Americans and 3,000 Japanese, does not tell the entire story. As the battle
progressed, the decisions made by Spruance and Yamamoto were based on the aircraft
carriers despite the sizes of their fleets; these, and their planes, pilots, and maintenance
crews were the pith of the battle’s importance. Based on this, American losses were one
of three carriers, or 33 percent, and Japanese losses were four carriers, or 100 percent.
Opinions of Spruance’s return to Point Luck follow.
Winston Churchill:
The victorious American commanders had other perils to face. The Japanese
Admiralissimo with his formidable battle fleet might still assail Midway. The
American air forces were sorely depleted, and there were no heavy ships capable
of successfully engaging Yamamoto if he chose to continue his advance.
Admiral Spruance, who now assumed command of the carrier group, decided
against a pursuit to the westward, not knowing what strength the enemy might
have, and having no heavy support for his own carriers. In this decision he was
unquestionably right…
