Eight of the force's officers drowned in the docks between 1913 and 1951, with other fatal casualties from being run over by a train, crushed under part of a ship's cargo and falling into a dry dock. The docks were badly hit during the Blitz and PC Robert Charles Winney and Sergeant Charles Edward Showell received posthumous King's Commendations for Brave Conduct in Civil Defence after being killed by an unexploded bomb on the night of 18-19 September. In 1992 the PLA Police was downsized, delimited to just the Port of Tilbury and given its present name – the other docks are now policed by the Metropolitan Police, particularly its Marine Support Unit.
