heavy bombers, began to receive intensive instructions from fifteen
crew members who had made the flight, while the remainder of the
I 9th Bombardment Group sailed back to the mainland.63
The allocation of a greater number of heavy bombers to the
Hawaiian Air Force than to any other overseas garrison in the spring
of 1941was an indication of a growing concern over the possibility
of war in the Pacific. It was also a testimony to the importance of
Hawaiian defense, an importance which stemmed both from the exist-
ence of Pearl Harbor naval base on Oahu and from the position of
the Hawaiian Islands in continental and hemisphere defense. The
duties of Army and Navy forces protecting the islands had been
clearly defined in joint defense plans. The principal joint task assigned
to forces permanently based in the territory was “to hold Oahu as a
main outlying naval base.” 6 4 In accordance with standard procedures
established for American forces on the continent and overseas, the
Army was to provide the mobile land and air forces required for
direct defense of the island coast lines against attack, while the Navy
was to conduct operations directed toward defeat of an enemy force
in the vicinity of the coast and to support the Army in repelling
attacks on coastal objectives. T o accomplish its mission the Navy was
charged with the provision and operation of “a system of offshore
scouting and patrol to give timely warning of an attack and, in addi-
tion, forces to operate against enemy forces in the vicinity of the
coast.” 6 5 It thus became the responsibility of the Navy to maintain
the long-range reconnaissance that would be required for advance
notice of an approaching enemy, but to the Army fell the operation
of an air warning system that would promptly alert all defense forces
against specific attacks by air. Since such a division of responsibility
called for close co-operation between the services, Army and Navy
commanders in Hawaii had agreed that if the threat of a hostile attack
were sufficiently imminent to warrant joint action, each commander
would “take such preliminary steps as are necessary to make available
without delay to the other commander such proportion of the air
forces a t his disposal as the circumstances warrant.” ”
These arrangements, it can easily be seen, were more theoretical
than practical, more general than specific. The need for a thorough
reconsideration of Hawaiian air defense led the W a r Department
General Staff in July 1941 to order that the AAF make a study of
