Alexander Fraser, 17th Lord Saltoun

Lieutenant-General Alexander George Fraser, 17th Lord Saltoun (22 April 1785 – 18 August 1853) KT GCH, KCB, was a Scottish representative peer and a British Army general who fought in the Napoleonic Wars and the First Anglo-Chinese War.

He served with the grenadiers in Sicily (1806), at Coruna (1808), on Walcheren (1809), and in Spain and France from 1812 to 1814. In 1815 Lord Saltoun commanded the Light Companies of the First Regiment of Guards (later the Grenadier Guards) in the Orchard at Hougomont on the morning of the Battle of Waterloo; and it was Saltoun who, later in the day, first noticed the Imperial Guard emerge from the hollow where they had been hiding all day, and drew the Duke of Wellington's attention to them. He was appointed a major-general in 1837 and commanded the first brigade in the Battle of Chinkiang (1842) and afterwards the whole force until 1843. He was further promoted to lieutenant-general in 1849.

He was appointed a Knight Grand Cross of the Royal Guelphic Order (GCH) in 1821 and a Knight of the Thistle in 1852. He was a Scottish representative peer from 1807 until his death and a Lord of the Bedchamber from 1821.
