Old Hickory has a mind like a steel trap to remember his position on 12SEP44. All the Best to you both.
When we were talking, gathering information for the book, he did very well. Some dates he knew to the day, such as when his friends were killed. Other incidences, he usually knew within the week. Sometimes he would say "Oh, that was after X, but before Y," then have to think a bit before pinning down a closer date. He said oftentimes that he did not know where he was, so it was hard to pin a date to a location.
I found the 30 Recon's After Action Reports after I had finished the first draft of the book and when I went thought it, I found that with one or two exceptions, he was on the mark about when things happened. There were a good many dates that I was able to verify using using the AAR, such as when he and another man captured 17 Germans in France in late August, 1944 and the time he thought he was about to be killed by a German tank. That last one, he had down to within 3 days before I could pinpoint it. He could not get any closer as he said the days had run together since they had been awake for a good part of time, even at night. That was in October, 1944.
Other dates I was not able confirm, such as when he ate cheese and crackers with a 8 or 9 year French girl in the drive across France. All he remembers is that it was after they crossed the Seine. A lot of the things he did in the race across Germany run together, too, except for the death of one of his good firends on 12 April, 1945 in a small village on the road to Magdeburg. That date he has never forgotten, nor 2 September, 1944 when another good friend and "the best soldier I ever knew" was killed near Tournai, Belgium.
I've started talking with publishers. We'll see how it goes.
