This islimited...there has to be more, but I just haven't come across it YET.
The 129th AAA BN was assigned to elements of the US VII Corps on at least three occasions:
4th Infantry Division, 9 July 44 / 10 July 44;
Battery D, assigned 11 July / 15 July 44;
9th ID, 14 July 44 / 18 July 44.
This limited number of assignments would not measure up to the total campaigns it participated in, nor cover the whole period of engagement.
My reference states:
9 July 44, The 4th ID and 83rd ID (VII Corps) advance towards Periers under a violent German barrage. 10 July 44, The three divisions of VII Corps, the 4th, 9th and 83rd, continue their offensive from the west. 11 July 44, The US First Army's offensive is now being carried out by all four corps at once, the VIII, VI, XIX and V, deployed on a front from the west coast of the Cotentin penisula to Caumont, about 13 miles east of St. Lo. 12 July 44, ...the VII Corps is in difficulties along the Cotentin-Periers road. 13 July 44, ...in the VII Corps sector only the 9th ID makes headway, while the rest of the line is virtually suspended. 14 July 44, The four corps of First Army (VII, VII, XIX and V) still advance south, meeting firm resistance all the time from the German 7th Army. 15th July 44, The offensive by First Army comes to a halt west of the River Taute. The offensive by 9th ID continues. 16th July 44, ...9th ID is opposed by the German 5th Parachute Division and the Panzerlehr Division. 17 July 44, ...9th ID overcomes German resistance and advances rapidly along the Periers-St. Lo road. 18 July 44, ..No entries for VII Corps this date. The reference states that 4th ID entered Luxembourg 13 Dec 44, and was subjected to the fury of the German Ardennes-Alsace Counteroffensive on 16 Dec 44. No mention or listing for the 129th AAA BN is noted. I'll try for "more light" later. LFT.
