Actually, he met an ex-Confederate Calvary Sergeant named LZ Walker, who, for a small sum allowed him to hop into his time transference machine and voila! He was onboard one of Her Majesty's ships and grabbed the piece from said Royal Marine, along with ammunition by the ton, and was "ZAAPPED!" yowee! back to 1873 so fast that Marine's head is STILL spinnin'! The ammo caused so muc trouble on the machine that said Honourable Irishman was coerced to buy drinks, freely, for said Sergeant for the remainder of the night!
