Lawford is an elegant dandy, monied, fashionable, aristocratic, representing everything Sharpe hates about the officer class - except Sharpe likes him, and does what he can to keep Lawford alive. Lawford learns what it is to be a true soldier from Sharpe, "God, you're ruthless" (Sharpe's Tiger). They forged a friendship that surpassed rank and class while in the dungeons of the Tippoo. Lawson and his uncle teach Sharpe how to read and write using a single page from Revelations Lawson had secreted in his pocket. After the defeat of the Tipoo, the two men are separated by the vagaries of the British Army.
They meet again in Spain in 1809 when Sharpe is a Lieutenant and Lawford is a Lt. Colonel on Wellington's staff. In Sharpe's view, despite Lawford's finery, he is a fighting soldier, and has his respect. After Sir Henry Simmerson disgraces himself by losing his colours, and Sharpe was gazetted captain of the South Essex Light Company, Lawford was chosen to explain the politics that would be brought to bear - the making of Sharpe as a scapegoat. At Talevera, Lawford takes command of the South Essex after Simmerson's disgraceful withdrawal from the line of battle. Promoted to Colonel, the Regiment was his.
In Sharpe's Company, Lawford loses an arm at Ciudad Rodrigo, and was repatriated to England.
Sharpe did not see Lawford again until he became embroiled in Fenner's crimping operation in Sharpe's Regiment. With a mind to his own political future, and Sharpe's advancement, Lawford tried to extricate Sharpe as gently from the situation as he thought he could and still avoid scandal.
