 The dockyard comprised a large storehouse, two blockhouses, a timber yard with a saw pit, and a wharf.The blockhouses flanked the yard, with Fort Amherstburg and the town of Amherstburg on either side, with the dockyard overlooking the channel which ran between it and Bois Blanc Island.The dockyard was further protected by defences constructed on the island which watched over the entrances to both ends of the channel.
