Sir Gregory Holman Bromley Way (1776–1844) was an English lieutenant-general.
Gregory, born in London on 28 December 1776, was the fifth son of Benjamin Way (1740–1808), FRS, of Denham Place, Buckinghamshire, MP for Bridport in 1765, and of his wife Elizabeth Anne (1746–1825), eldest daughter of William Cooke, provost of King's College, Cambridge. His grandfather, Lewis Way (died 1771), director of the South Sea Company, and descendant of an old west-country family, first settled in Buckinghamshire. His aunt Abigail was the wife of John Baker-Holroyd, 1st Earl of Sheffield.
His brother, Lewis Way (1772–1840), was the father of the antiquary Albert Way (1805–1874).
He died at Brighton on 19 February 1844, and was buried in the family vault at Denham Church, Buckinghamshire. Way married, on 19 May 1815, Marianne, daughter of John Weyland, of Woodeaton, Oxfordshire, and Woodrising, Norfolk. He had no children.
He entered the army as an ensign in the 26th foot (Cameronians) in 1797. He was captured by French privateers when he was on his way to join his regiment in Canada, and was detained a prisoner in France for a year before he was exchanged. He was promoted to lieutenant in the 35th foot on 3 November 1799, and sailed with his regiment in the expedition under General Pigot on 28 March 1800 for the Mediterranean. Arriving at Malta in June, he took part in the siege of Valletta, which ended in the capitulation of the French on 5 September. He returned to England in 1802, and was promoted to be captain in the 35th foot on 13 August of that year. Shortly after that, he was placed on half-pay on reduction of that regiment.
Way was brought in as captain of the 5th foot on 20 January 1803, and, after serving in the Channel Islands, embarked with his regiment in the expedition under Lord Cathcart for the liberation of Hanover in 1805; but the vessel in which he sailed was wrecked off the Texel, and he was taken prisoner by the Dutch. After his exchange he sailed at the end of October 1806 in the expedition under Major-general Robert Craufurd, originally destined for Chile, to Cape de Verde, St. Helena, and the Cape of Good Hope. In accordance with orders received there, the expedition sailed for the River Plate, arriving at Montevideo in the beginning of June 1807, where it joined the force under General John Whitelocke, of which Way was appointed assistant quartermaster-general. At the storming of Buenos Ayres, Way led the right wing of the infantry brigade. He returned to England after the capitulation.
