A great 52-minute video has just been made of the contribution of the 16th Engineers in WWI by a Dennis Skupinski. Eugene (Gene) was made a major.

For quick reference, the scenes with a mustached Eugene. I. Van Antwerp are into the documentary at the following times:

4:10 – observing innoculation

14:48 – on a horse, erroneously called Major Robertson

41:07 – front of line marching men

45:46 – showing then and now where the men marched

(My cousin Mike Denton also believes you might find him at the 9:03 mark in the back row, 11th from the left, in the Officers Corps picture.)
