per cent of all search operations in the area. Total compliance would
have completely disrupted the striking force which the bomber com-
mand was obligated to maintain in order to attack enemy naval craft
or installations within its radius of action. Both naval and military
forces were operating below their authorized strength, and regardless
of desires for mutual assistance and plans to that end, the Caribbean
area was sadly deficient in the matter of aerial overwater reconnais-
sance.
T h e vital importance of this phase of canal defense was revealed
in an estimate of enemy capabilities prepared by the Caribbean De-
fense Command in the latter part of November 1941.Japan was
regarded in respect to the canal itself as the primary potential enemy,
and a carrier-based attack from the Pacific was considered “not an
improbable feat.” Other possibilities were taken into account, but it
was concluded that in any event the most important defensive meas-
ure was “increasing and thorough reconnaissance and observation of
the air, sea, and land approaches to the Canal Zone.” Existing forces
in the area were regarded as sufficient to repel any probable initial
attack on the canal provided they were given timely warning of the
approach of hostile forces. T h e inability of defending naval and mili-
tary air forces to perform the required amount of reconnaissance and
to provide the “timely warning” constituted perhaps the chief weak-
ness in Caribbean defense immediately prior to American entry into
the war. It was a weakness which was recognized by both Army and
Navy commanders; their expressed hope lay in the postponement of
attack by an enemy until the defending forces could achieve the
proper degree of co-ordination and the necessary equipment for
complete coverage of the vast sea frontiers.
T h e emergence of the air weapon as the predominant element of
Caribbean defense was not unnatural in the light of the European
war and the geography of the area. T h e experience of Great Britain
and other countries at the hands of the Luftwaffe had affected the
growth of American air power in general and the strengthening of
overseas garrisons in particular. T h e climax of prewar air preparations
in the Caribbean occurred in September with the elevation of General
Andrews from his post as head of the air force to that of the Carib-
bean Defense Command, marking the first time an airman had ever
commanded all Army forces in the area. T h e Caribbean Air Force,
now under the command of Maj. Gen. Davenport Johnson, was not
