What does the US Army do while the fleet sails west?

What would the US Army be doing in this scenario?

It would continue defending Hawaii and Pearl Harbor rather than send divisions with the fleet.

The Navy would not take Army divisions along as passengers on this fleet movement. The US Army was still building its wartime mobility and had no ready formation that naturally belonged with the diplomatic sortie. Army units would continue their existing defensive duties in Hawaii and at Pearl Harbor. Reinforcements moving toward the Philippines would travel through separate plans and channels instead of turning the battle-line demonstration into a joint landing force.
