Not so much typos, but continuity problems created by my newer books had to be addressed; e.g. the sixth-rate Frigate Dido had too many appearances in other stories and was replaced with a sister ship. Also, pre-1802, a junior captain wore a single epaulet on his right shoulder. After that, junior captains sported two epaulettes distinct from those of senior captains. It's piddly stuff, but if you bought the story already, the update is free and you are welcome to it.
P.A.
