Portland is the Naval Base at Portland, Dorset, near Weymouth - highly unlikely to be Portland, Oregon.
HMS Inflexible was a new Battlecruiser, one of two that took part in the Battle of the Falkland Islands on 1/12/14.
Acheron was at that date a training ship, a conversion of the old ironclad Northumberland, dating from the 1860's. A destroyer of that name entered service in 1911, so probably just too late to be the one your man was in. There many vessels called Acheron going back to the 17th century; the French also used the name - as in the film "Master & Commander". The last British one was a post WW2 submarine.
Pembroke II was a shore base, at Portsmouth I think.
We can only speculate as to the human story; there were many reasons not to take to Navy life at the time.
