She published an autobiography in 1857
In order to provide Mary with some degree of financial means with which to live out the remainder of her life, the press was made aware of Mary's condition and numerous fundraising initiatives were organized.
The Wonderful Adventures of Mrs Seacole in Many Lands, Mary's autobiography, was originally published in 1857, making her the first black woman in Britain to write and publish an autobiography. She mostly dictated to an editor who fixed her punctuation and spelling. The book goes into great depth about her unusual life and ends with a description of her adventures in the Crimea as her "pride and delight." 1881 saw her passing in London.
The troops started to disperse on March 30, 1856, when the peace treaty was signed. Day and Seacole had already brought some cheap supplies. She returned to England penniless since they were compelled to auction them off for lower than anticipated amounts. To help her pay off her obligations, service members put together a fundraiser, but it wasn't enough. Seacole wrote her memoirs Wonderful Adventures of Mrs. Seacole in Many Lands in order to raise more money. The book achieved bestseller status. Queen Victoria also contributed to the Seacole Fund by starting a second one, which brought in enough money for Seacole to live out the rest of her days comfortably.
