This is the last letter written by Lord Nelson, and addressed to Lady Hamilton. The image is one from our collection. The text below is from official sources. The two don't match.

"My Dearest beloved Emma, the dear friend of my bosom,
"The Signal has been made that the Enemy's Combined fleet are coming out of Port. We have very little Wind, so that I have no hopes of seeing them before to-morrow. May the God of Battles crown my endeavours with success, at all events I will take care that my name shall ever be most dear to you and Horatia, both of whom I love as much as my own life, and as my last writing before the Battle will be to you, so I hope in God that I shall live to finish my letter after the Battle.
"May Heaven bless you, prays your
"Nelson and Bronte."

Under which, in another hand (possibly Emma's), is written:
"This letter was found open on his desk & brought to Lady Hamilton by Capn Hardy

"Oh miserable wretched Emma
"Oh glorious & happy Nelson"
