James Hay, Lord Hay

James Hay, Lord Hay and Lord Slains (7 July 1797 – 16 June 1815) was a British Army officer and Scottish aristocrat killed during the Waterloo Campaign.

Hay, an ensign in the 1st Foot Guards, was killed at the Battle of Quatre Bras while serving as aide-de-camp to General Maitland.

In 1899, Murray's Magazine published some recollections by Georgiana, Dowager Lady De Ros (a daughter of the Duchess of Richmond) about the Duchess of Richmond's ball that took place on 15 June 1815, the night before the Battle of Quatre Bras.

She recalled "I remember being quite provoked with poor Lord Hay, a dashing merry youth, full of military ardour, whom I knew very well for his delight at the idea of going into action, and of all the honours he was to gain; and the first news we had on the 16th was that he and the Duke of Brunswick were killed".
