Outstanding post K&K. A lot of people came through Camp Mills (Garden City) and Upton to get sent into that brutal conflict. A few years back a few guys whom I served with in a NY ARNG unit went to go tidy up a memorial just south of the Clinton St. station on the Garden Secondary, and we were pleasantly surprised to see the locals kept it immaculate, and came together on Vet's Day to remember those who went through Camp Mills. One such person was Joyce Kilmer, a poet ("Trees" and "Rouge Bouquet", about some fellow soldiers who perished in a trench and the members of the 42 ID read it over each funeral. Eventually they read it over Kilmer's grave not long thereafter). The current CO of the 1/69th carries the crucifix he wore when they are deployed, and unfortunately they have been more "over there" than here the last 2 decades.
Another one was Father Duffy, many of you have seen his statue in Times Square, across from the TKTS kiosk, who started as a chaplain in a unit in the Spanish American war, and was at Montauk when they returned at Camp Wikoff. He survived WW I and served in a nearby church in NYC until his passing. And all rode the rail - "Lest we forget!"
