The Invasion of San Martin took place in 1883 PD, when the People's Republic of Haven invaded the Trevor's Star System and conquered the planet San Martin. Their main goal was to secure the local terminus of the Manticore Wormhole Junction.
The People's Navy destroyed the San Martin Navy. The last battle of the SMN occured when Commodore Jesus Ramirez' command covered the final civilian evacuations to Manticore. Commodore Ramirez was defeated and captured in the battle, but managed to destroy three times more Havenite warships, than number of units he commanded.
