Good morning,
You don't know how excited I was to find my Dad's name in Mr. CasaGrande's first post.
I have the dates on which we entered the different places etc., also a list of over eight hundred names and addresses ( for that time ). For instance, Harry J Drake - RD 1, St Ignatius, Montana. All members of the 343rd.
I went searching for 343rd Engineers topics a little over a year ago, and could find very little. This time when I did a Google search I found a GOLD MINE. 
The main reason for my search is to try to obtain documentation of an incident where Dad's convoy and his vehicle were hit during the offensive into Messina. B Company, or at least some of them, had been detailed to deliver equipment and supplies to British troops near Messina. Dad's convoy was the last one and his was one of the last vehicles. It appears that Dad and one other person were the only ones to survive the hit. Dad was unconscious, but no obvious wounds. The injuries were more to hearing, back, and concussion. He was evacuated to a British Field Hospital, where he was left to be treated after the more seriously wounded. A British patrol cycle came by and said his unit was being moved. Dad hopped on the cycle and went back to his unit. Mind you he was still working on "Autopilot." You know soldier's!! Even if they are missing a limb, they want to get back with their "family." Dad states that it was about 10 days that he really didn't know where he was, or who he was. When he regained awareness, he was sitting in a tank engine (I think) cleaning the injectors. Dad has suffered from PTSD "forever" and there isn't a week that he doesn't wake up with nightmares at least a couple of times.
There are several names that Dad mentions, but at the moment the only one I can remember is last name of Lively, first name maybe begins with an A.
Dad now lives in Kennewick, WA, and with the help of my borther and myself is still able to live at home. He lost his lifelong partner last July 3 days short of their 60th wedding anniversary. It was a great blow to all of us.
I am lucky to have originals of several of the commanding officers letters, troop orders, etc.. I would be happy to share these with anyone if they are interested. I could provide them as PDF documents if wanted.
Thank you so much for this wonderful historical site.
Take care, have a great day, and GWG,
Ardis Kenney (Drake)
