On the deck of the Conqueror, General Cordington passionately introduced to Arthur the city emerging on the horizon and its long history.
It was indeed the base of the Channel Fleet and the oldest naval base in the history of Great Britain—Portsmouth Naval Base.
As the birthplace of the Royal Navy, Portsmouth Naval Base carried a fine tradition of foreign combat.
Even during the Roman Empire, Portsmouth had already been established as a fortress, and Parchester Castle to the north of the harbor was one of the remnants left by the Romans.
In the subsequent Viking Age, it served as a frontline fortress against Viking invasions.
By the 14th century, during the Hundred Years' War between England and France, Portsmouth acted as the forward base for the Plantagenet dynasty's operations against France.
Its naval tradition began in 1496 with the founding of the Portsmouth Naval Shipyard, and in 1540, the Royal Navy officially declared its establishment there.
