HMS Vanguard was Nelson's flagship at the Battle of the Nile.
Nerot's Hotel (or Hotel Nerot, London) opened in 1776 in King Street on the site of the former townhouse of the Earl of Ranelagh. It was a very fashionable hotel and Nelson met his wife and his father there after his return in 1800 from the Battle of the Nile. It relocated to Clifford Street in 1811, with the original building being demolished in 1835 and the St James Theatre being built on the site.
One of Winston Churchill's hobbies was writing for movies as ghost writer. He wrote two of Nelson's speeches, as propaganda pieces against Germany, which was invading Europe at the time the movie was filmed and released.
Reportedly Winston Churchill's favorite movie. He claimed to have seen it 83 times.
