He then joined BBC's Nationwide and was promoted to become head of current affairs at BBC Northern Ireland. He then joined Thames Television as editor of Thames News. He relocated to the United States in 1980 after marrying an American. Unable to get a green card, he started writing novels, as this did not require a work permit.

Struggling to come up with a name as distinctive as Horatio Hornblower, he used a placeholder based on the rugby union player Richard Sharp; eventually, he kept it, just adding an "e". [1] The author had intended to write 11 novels, the same number as in the Hornblower series, ending with Sharpe's Waterloo, but later changed his mind and continued writing.In his historical note, Cornwell comments that, aside from Sharpe, a fictional character, he is aware of only one person who was present at both Trafalgar and Waterloo: Miguel de Álava, originally a marine in the Spanish Navy at the time when Spain was allied with France, later a general and close personal friend of the Duke of Wellington, and Spanish ambassador to the Netherlands.

The story opens with Sharpe in India, having been there several years but now about to return to England having joined up with the 95th Rifles. He' an ensign, a low ranking officer promoted out of the ranks. Being wise to the ways of crooks, he helps out an English naval officer who had been cheated out of several hundred pounds. Apparently it was the practice of travelers to bring their own furniture when traveling by ship and there existed a thriving business reselling furniture of those who had recently arrived from England and no longer needed the equipment they had used on the voyage. Sharpe is described as "brilliant but wayward" in Sharpe's Sword, and he is portrayed by the author as a "loose cannon". He becomes a highly skilled and experienced leader of light troops. In contrast to the honourable Horatio Hornblower, the inspiration for the series, Sharpe is a rogue, an unabashed thief and murderer who has no qualms about killing a bitter enemy when the opportunity arises. However, he is protective of women in general and has a number of lovers over the course of his life. Richard Share was a feral London boy before he joined the British army. In the time just before this book, he was sent to India to battle both indigenous peoples and other countries with imperial ambitions. He saves the life of an officer (who later will become Lord Wellington, hero of Waterloo) and is promoted from the ranks to ensign.Sharpe serves four uneventful years as a sergeant. In 1803, he is the sole survivor of a massacre of the garrison of a small fort carried out by a turncoat Company officer, William Dodd ( Sharpe's Triumph). Because he can identify Dodd, Sharpe is taken along by McCandless on a mission to capture and punish Dodd, to discourage others from deserting. Their search takes them first to battles at Ahmednuggur and then Assaye. Chase invites Sharpe to transfer to his ship; Sharpe is reluctant to accept, until he discovers that Lord Hale has insisted on switching to the faster Pucelle, along with his wife. Chase confides to Sharpe that a French agent, probably Dornberg's "servant", negotiated a secret treaty with the ablest of the Indian Maratha leaders. If it is delivered to Paris, the French might send arms to the Marathas to start a new war against the British. XIX век си е било истинско изпитание, например от Индия до Европа за това са били нужни няколко месеца - без да се къпеш, с оскъдна и гадна храна, без почти никакво лично пространство и не само бедните, а и богатите са пътували в подобна обстановка.
