After You got a Strange Key From that Town with Infected.. You get into a Room with a Canon and an Vent Up the Roof.. A British soldier Comes up to the Vent on the Other Side.. He says.. "Hello.. I think I’ve got the attention of that ship over there.. I can lower this platform and get us down there" After a couple Minutes he Lifts the Platform using a Winch.. But He gets tackled by a Runner.. You Use the Key to Unlock the Vent.. with a Musket in Hand.. the British soldier Screams for Help. and He Tried not to Get his Neck or Any part of His body Bitten.. You Should Really Help him by Killing the Runner..
