His first assignment as an ensign was aboard the USS Gettysburg, where he became friends with David Gold. Six months into his assignment, he took shore leave at Cathius IX, and while there, was conned into a game of chance where he soon ran up a large debt. When he refused to pay, he was beaten to death by the Gallamite gamemaster, the Katcherian casino manager, and their Mausetite guard. An automatic transporter recall was activated when his life functions ceased, and he was beamed back to the Gettysburg and revived.
After six months rehabilitation, he was reassigned to the USS Tian An Men. Three years later, after becoming a lieutenant, Silver tracked the Katcherian to Argelius II, intent on taking revenge. However, when he learned the man had changed his life, he let him live.
Six years later, Silver had reached the rank of lieutenant commander and was serving on the USS Venezia. At that time, Silver tracked the Gallamite to the planet Carnegie, but upon discovering he'd become a legitimate businessman, refused his offer of a bribe, insisting he give it to his employees instead.
A few years later, Silver was promoted to captain, and before taking command of his first ship, learned the Mausetite was in prison on an unaligned planet facing the death penalty. Silver bought the right to determine the method of the prisoner's death, but rather than exercising it, gave that right to the Mausetite as payment of his old gambling debt.

- Given the nature of the Captain's Table tales, and the characterization of David Gold's tale as a parable, it is questionable how much if any of Abraham Silver's story is "real," or if he was in fact a real person. It is also possible that Captain Gold was using the story of Mr. Silver to impart a somewhat embarrassing tale from his own life.
