Hi Marion!
In correspondence from Captain Fallon he did say "Our own regiment spent more than 50% of our time in WWII fighting as infantry and you rarely see mention of this even in the official histories." I don't know how many replacements there were, but the 36th Engineers that were in the entire war should be entitled to the CIB based on their combat time. I came across the thread with some controversy over that and don't intend to offend anyone.
I've been doing a write-up just for family to better understand Dad's role in the war. It's six pages and the best I can do with info at-hand. Wow, do I envy you sitting on all those stories and information. Did you find lots more in the national archives? The Adjutants History linked on John Fallon's page is very good for a timeline of activities, however colorless and incomplete. I really like Carlo D'Estes' compassionate style of writing—got me crying several times.
Can't wait for the documentary and book. I know your work will be excellent. The book will be well worth the wait if it contains the rich detail that I'm craving. Do you know where I can find data on the 36th Engineers KIA, WIA, MIA and total number of bridges built during the war?
Peanuts,
36th Engineer Daughter
