Dad had some lead shot in his collection but all of it was from a site west of Poteet on the Atascosa river at one of the several Camino Real crossing.Unfortunately, the archaeologist Bob Moses died while still a pretty young man... He had some very detailed research notes and so on about his attempts to locate the battlefield, which to date remain un-published.
Somewhat ironically, I've been trying to help a young man whose WWII veteran grandfather--since passed--found what may have been a 12-pounder ball at La Villita way back in 1939 or 1940... No idea what ever became of the cannon ball. Probably in a private collection.
They live on several occassions beginning in the depression, in those blackjacks west of Leming. ( my great aunt was the postmistress for years in Leming) but they never mentioned finding anything other than the usual stuff like flint projectile points. But you know how that sand is there in that encinal. Deep!!!! And always hiding it’s secrets.
