I suggest you write to the National Archives and Records Administration. They are the depositories of all Federal agency records. If there was an official history written about this organization, it may be stored there.It would help if you can define what type of unit is that. Is the 359th Army Engineers a battalion or a regiment? I suspect it is a battalion.
I wanted the history of my father's battalion, the 762nd AAA Gun Battalion, formed in Panama Sept 1943, and disbanded Ft Bliss, TX Sept 1945. NARA College Park had it, I ordered it the copy cost $75.00. I also got the history of the 891st AAA Gun Battalion, also formed at the same time in the other side of Panama. Both battalions returned to the US through the New Orleans Port of Embarkation Sept 1944, and served together until the end. The 891st was disbanded same date and place than the 762nd.
I am still waiting on the 766th AAA Gun Battalion, where an uncle served.
