Did US Army have War Diaries in WW2 … (?)

[Michael Ockenden]

I’m trying to find out about the 129th Signal Radio Intelligence Company. They were part of the 6th Army Group in the European Theater of Operations, US Army. I also have a note that the 129th was assigned to the Fifteenth (15th) Army.

The company took part in the Ardennes-Alsace Campaign, and was in the Rhineland.

From 2 May - 31 October 1945, the unit was in occupied Germany.

As mentioned in ‘Canucks by the Sea – The Canadian Army in Eastbourne during the Second World War’, in March 1944 the unit operated a radio intercept station near Eastbourne in East Sussex, England.

Someone has provided the following passing reference to the 129th SRIC:-

"The 3262d Signal Service Company was activated in England on 9 November
1944 ... 1st Lt. Fred T. O'Day, 01638182, who had been designated as
commanding officer, returned from his former assignment with the 129th
Signal Radio Intelligence Company in France and assumed command on the same
date.”

Will I be able to find official war diaries, as with British and Commonwealth forces? If so, where?

I presume there must be a US Army forum similar to MLU and 'Canadiansoldiers.com'; can someone pse advise? Perhaps I can find out if there is an official history and locate some former members of this unit.

Comments greatly appreciated …
