A monument was erected to his memory in the cemetery of the church of Etienne, Bayonne, with the following inscription:—
This tomb is placed here By the officers of the 3rd battalion, 1st, or Royal Scots Regiment of Foot, As a testimony of respect to the memory of The late Major-General Andrew Hay, Commanding the First Brigade of the Fifth Division of the British Army in France, Who gallantly fell on the morning of the 14th of April, 1814, In defence of the ground in which His body is deposited, Aged 52 years.
Near the north door of St. Paul's Cathedral, London, a monument has also been erected to the memory of this gallant veteran. He is represented falling into the arms of Valour, with a soldier standing, lamenting the loss of his commander.
[125] "The 3rd battalion of the Royal Scots distinguished itself in a particular manner. Being removed from the centre of the 5th division, it charged and routed a column of the enemy. It was then formed in a square, to receive the cavalry, and though repeated attacks were made, not the slightest impression was produced. Wherever the lancers and cuirassiers presented themselves, they found a stern and undismayed front, which they vainly endeavoured to penetrate."Mudford's Historical Account of the Campaign in the Netherlands in 1815.
[126] "Though charged six or seven times by an infinite superiority of numbers, the French cavalry never for an instant made the slightest impression upon the square of the Royal Scots."Narrative by an Officer who was an eye-witness.
