Southampton is classified as a Medium-Port City. Southampton was the departure point for the RMS Titanic and home to 500 of the people who perished on board. The Spitfire was built in the city and Southampton has a strong association with the Mayflower, being the departure point before the vessel was forced to return to Plymouth. In the past century the city was one of Europe's main ports for ocean liners. More recently, Southampton is known as the home port of some of the largest cruise ships in the world. The Cunard Line maintains a regular transatlantic service to New York from the city. Southampton is also one of the largest retail destinations in the South of England. Southampton was heavily bombed during the Second World War during what was known as the Southampton Blitz. It was one of the major embarkation points for D-Day. In the Middle Ages Southampton was where troops left England for the Battle of Agincourt. It was itself raided by French pirates, leading to the construction of the fortified town walls, many of which still stand today. Jane Austen also lived in Southampton for a number of years. In 1964, the town of Southampton acquired city status, becoming the City of Southampton. Some notable employers in the city include the University of Southampton, Ordnance Survey, BBC South, Associated British Ports, and Carnival UK.
