Cartwright, Labrador

On 8 Feb 1952, the 373d Trans Major Port was assigned to the Corps of Engineers for the purpose of planning, phasing and controlling the discharge of all cargo destined for Operation SUNAC (Support and Supply for North Atlantic Construction).

Since the operations encompassed an area too large for effective centralized command, Sub-Ports were organized as of 11 March 1952 and the duties connected therewith delegated to Sub-Port Commanders. The Provisional Sub-Port Gypsy, later changed to Sub-Port Pine Tree, and hereinafter referred to as same, was given the task of six Pine Tree sites extending from St. Anthony, Nfld. to Frobisher, Baffin Island, and was under the command of Lt. Col. James C Sherman.

Due to the nature of the operations assigned to Pine Tree, with respect to the shipping season for individual sites, it was decided to further break down the Sub-Port into two Task Teams with identical organizational structures. (Chart #1, attached). The operational dates and responsibilities for sites were to be as follows:

Task Team #1 (Det. #4)

Task Team #2 (Det. #5)

The above teams (Dets. 4 & 5) were to work these sites consecutively and simultaneously with operations commencing at each site on or about the above dates.
