 It was originally written for British newspaper "The Daily Mail" which serialised it during the Christmas season of 1994.

Sharpe's Peril is a British TV film from 2008, usually shown in two parts, which is part of an ITV series based on Bernard Cornwell's historical fiction novels about the English soldier Richard Sharpe during the Napoleonic Wars.
 Contrary to most parts of the TV series, "Sharpe's Peril" isn't based on one of Cornwell's novels.
 Both are set in 1817, two years after Sharpe has retired as a farmer in Normandy, so chronologically they come after "Sharpe's Waterloo" (1815) and before the final novel "Sharpe's Devil" (1820–21).
 In "Sharpe's Challenge" and "Sharpe's Peril", Sharpe and his comrade in arms, Patrick Harper, have been temporarily called out of retirement and asked to go to India.
The Fort is a historical novel written by Bernard Cornwell.
 The book relates to the events of the Penobscot Expedition of 1779 during the American Revolutionary War.
 While centred on the efforts of a regiment of Scots to establish and hold the fort against superior numbers of American revolutionaries, it contrasts the actions of two military icons: John Moore (later Sir John), a young officer who later laid the foundations of the light infantry doctrine used by the 95th Rifles and others against the French in the Revolutionary and Napoleonic Wars; and Paul Revere, hero of Longfellow's poem written two generations later but, according to Cornwell's research, an insubordinate, unreliable and probably dishonest character who was a major factor in the defeat of the Americans.
Sharpe's Christmas contains two short stories, "Sharpe's Christmas" and "Sharpe's Ransom", written by historical fiction author Bernard Cornwell.

 Originally, the first short-story, "Sharpe's Christmas", was written for British newspaper "The Daily Mail" which serialised it during the Christmas season of 1995.
 Later, in an effort to raise funds for The Bernard and Judy Cornwell Foundation, an extended version was published by The Sharpe Appreciation Society in 2003 to add "Sharpe's Ransom" into a collection of the two short stories simply titled Sharpe's Christmas.
Sharpe's Challenge is a British TV film from 2006, usually shown in two parts, which is part of an ITV series based on Bernard Cornwell's historical fiction novels about the English soldier Richard Sharpe during the Napoleonic Wars.
 Contrary to most parts of the TV series, "Sharpe's Challenge", as well as the follow-up "Sharpe's Peril", isn't based entirely on one of Cornwell's novels, but it uses and adapts some characters and storylines from "Sharpe's Tiger".
 Both are set in 1817, two years after Sharpe has retired as a farmer in Normandy, so chronologically they come after "Sharpe's Waterloo" (1815) and before the final novel "Sharpe's Devil" (1820–21).
 Some of the events in the film are, however, inspired by events in the first three novels of the series.
 In "Sharpe's Challenge" and "Sharpe's Peril", Sharpe and his comrade in arms, Patrick Harper, have been temporarily called out of retirement and asked to go to India.
