Henry Brennan was an English seaman on board the Obra Dinn during her last voyage in 1802. He was killed by Captain Robert Witterel in his attempted mutiny.


Brennan was selected for the firing line performing the execution of passenger Hok-Seng Lau and was the only member to actually hit the condemned man.[1]

After surviving both the crab rider and Kraken attacks, Brennan joined First Mate William Hoscut, topman Lewis Walker, and Captain Robert Witterel in intervening when topman Leonid Volkov attempted to prevent surgeon Henry Evans and his party from escaping. Meanwhile, Midshipman Thomas Lanke overheard Gunner's Mate Olus Wiater and Fourth Mate John Davies broach the subject of mutiny and panicked at the top of his lungs. Wiater stabbed him in the back, but he and Davies wrestled for the gun and had his face blown off. The resulting dust-up attracted the attention of Hoscut, who ran to Lanke's aid; and Brennan, who, thinking Davies shot Wiater with malice aforethought, promptly clubbed him.

Some time later, Hoscut, Brennan, and Walker all planned a mutiny and attempted to extort shells that Captain Witterel allegedly had. Brennan demanded the location of the shells, and Witterel revealed that he threw them overboard. Brennan attacked him anyway, but he got his throat slit.

The East India Company insurance assessment on the Obra Dinn incident found Brennan guilty of murder of a crewmate[2] and attempted mutiny. His estate was fined £50.[3]


Brennan can be identified after Escape, part 6, where First Mate Hoscut addresses him by name, telling him to get the surgeon's kit for wounded Midshipman Thomas Lanke. Brennan cups his ear after he has been called.


Seaman Brennan looks as if he's never seen a spear-wielding dark rider on a giant crab emerge from the ocean before (in Soldiers of the Sea, part 2).

Brennan appears in seventeen memories, more than any other character. Chronologically, he first appears in Loose Cargo, part 1. He perishes in The End, part 2 and appears in the Justice at Sea sketch. His corpse was one of the few that remained on the ship when she drifted back into port in 1807.
