Lieutenant General Humphrey Bland (1686 – 8 May 1763) was an Irish professional soldier, whose career in the British Army began in 1704 during the War of the Spanish Succession and ended in 1756. First published in 1727, his Treatise of Military Discipline was the most successful and widely used military drillbook to appear in English during the 18th century. It was reprinted nine times between 1727 to 1762, George Washington being among those who owned copies.
