SEW F be the firing pi.. s for the weapons. Construction of the causeway to link the islands of .Aomon and Biijwi was in preliminary stage. In the meantime, agreement had been reached with the State Department on 19 December that a danger area would be declared around Eniwetok, extending 100 miles east and west and 75 miles north and south from the center of the atoll. This was the area that had been decided upon as offering a reasonable safeguard against dangerous radioactive contamination and unwanted observation. This action was publicly announced on 30 December. All foreign governments were formally advised of this action, as were domestic agencies such as the Hydrographic Office. General Hull returned from the Forward Headquarters at Fort Shafter to Washington on 13 December. After orienting the staff, he stated at the regular conference that the Task Force had now passed from a planning to an operating stage. At the staff conference on 19 December, General Hull announced that he would return to Oahu that day and would again visit the forward area early in January. At that time he announced that JTF Main would close in Washington on 15 February and open at Fort Shafter, Oahu, T. H., at the same time. A Rear Echelon would open on 16 February in the control section of the Plans and Operations Division, Department of the Army.

General Hull did not return to Washington after his departure on 19 December until after completion of the operation. During the period 4 to 9 January 1948 he again inspected the progress of construction at Kwajalein and Eniwetok. At Kwajalein various details were gone over with Captain Vest, Island Commander. It was decided that Captain Vest should be furnished a Letter of Instructions to include: 1. An outline of construction to be undertaken and priority of accomplishment. (Some construction was underway at this time. ) 2. An outline of the command and responsibility agreements. (Colonel Barney was to be a Deputy to Captain Vest. ) 3.
