At the site where his son David Westphall and his Platoon were ambushed and killed, near Con Thien in 1968, Dr. Westphall emptied his container of New Mexican soil and filled it with Vietnamese soil. This he carried back home and put on the Memorial grounds near the Chapel.
This map shows the general area northwest of Dong Ha, almost directly north of Cam Lo, where the ambush, and later the soil exchange, probably took place.
