Former dogface soldier of the 3d Infantry Division here. Doing some research for a military-history related project I'm working on and while I have found various CMH publications to be of enormous value, I've come across something that is either incorrect, or completely confounding me. I'm really hoping one of my fellow researchers here might have some guidance! Short version: The 77th Infantry Division seems to have different campaign credits across multiple CMH publications. I've reached out to the CMH (U.S. Army Center of Military History), but have not yet heard back from them. They say they are understaffed right now because of COVID, so who knows. In the online combat chronicles section of the CMH site, they are given campaign credit for the Western Pacific, Ryukyus, and Southern Philippines, and campaigns, but with no arrowhead devices for any of them However, in another publication by the CMH (the classic "Armies, Corps, Divisions, and Separate Brigades", CMH Pub 60-7), they are given credit for the Western Pacific, Ryukyus, and Leyte campaigns, and the Leyte campaign has an arrowhead device. So the campaigns themselves are in conflict, as is the assignment of the arrowhead device. Now, I know the Combat Chronicles uses data taken from "The Army Almanac: A Book of Facts Concerning the Army of the United States", published in 1950 by the U.S. Government Printing Office. And CMH Pub 60-7 was published in 1999. So one 5 years after the war ended (fresher), and the other 54 years after (perhaps additional info came to light or changes were made?). So, I consulted (what should be) the one true primary source document, which is the campaign register (DA PAM 672-1). The campaign register shows: Western Pacific, Ryukyus, and Leyte as the campaigns, so I assume those are correct (or at least were at the time), and that the Combat Chronicles/Army Almanac may be in error there. It also shows several assault landings associated with those campaigns, with some caveats. This document only exists at this point as a bunch of scanned pages, but this is what the encoding of the all-important column 5 looks like for the 77th Infantry Division's campaigns. A - Yakabi Shima, 26 Mar 45, WD GO 109-46, Det, Hqs only A - Zamami Shima, 26 Mar 46, Det, Hqs Special Troops, MP Platoon only A - Geruma Shima, 26 Mar 45, WD GO 109-46, 1st Info & Hist Svc, Team C and Det, Hq & Hq Btry only A - Hokaji Shima, 26 Mar 45, WD GO 109-46, Det, Hqs Spec Trps, CIC Det. only A - Ie Shima, l6 Apr 45, WD GO 109-46, 1st Info and Hist Svc, Team C; Det, Hqs Co and Det, Hqs only; See roster in Office of The Adjutant General A - Ormoc, Leyte, 7 Dec 44. WD GO 109-46, Band; Hqs, Special Troops; Hq & Hq Co & Med Det; Det; Military Police Platoon and Det, Hq & Hq Btry, Div Arty, only. Keeping in mind that arrowhead devices apply to individual ribbon display, as well as on unit campaign streamers, as applicable.... The way I read it above, only members of the subordinate units in italics would be eligible to wear the arrowhead device for an assault landing at Leyte (and I suppose the other campaigns related to the other assault landing entries above). So why does the entire division reflect an arrowhead device for the Leyte campaign streamer in CMH Pub 60-7? Sorry this is a long post, but I can't seem to find an answer to this online anywhere. Thanks so much for any guidance!
