Minden Day is a regimental anniversary celebrated on 1 August by certain units of the British Army. It commemorates the participation of the forerunners of the regiments in the Battle of Minden on that date in 1759.
The celebration of the day involves the wearing of "Minden Roses" on the regimental head dress, and, in the case of the infantry regiments, the decoration of the regimental colours with garlands of roses. This recalls that the regiments wore wild roses at the battle that they had plucked from the hedgerows as they advanced to engage the enemy.
Minden Day is celebrated by:
- 12 (Minden) Battery, 12 Regiment (Royal Artillery)
- 32 (Minden) Battery, 16 Regiment Royal Artillery
- The Royal Scots Borderers, The Royal Regiment of Scotland, as successors to the 25th Regiment of Foot (King's Own Scottish Borderers)
- 1st Battalion, The Royal Anglian Regiment, successor to the 12th Regiment of Foot
- HQ Company, 3rd Battalion, The Royal Anglian Regiment (Army Reserve)
- The Royal Regiment of Fusiliers, successor the 20th Regiment of Foot
- The Royal Welsh, successors to the 23rd Regiment of Foot
- The Princess of Wales's Royal Regiment, successors to the 37th Regiment of Foot
- 3rd and 5th Battalions The Rifles Regiment as successors of The Light Infantry, successors to the 51st Regiment of Foot
- The North Saskatchewan Regiment [Reserve Canadian Army] successors to the Saskatoon Light Infantry in honour of a regimental twinning with a British Army Regiment. The N.Sask.R. wears the white rose.
The colours of roses varies: red is used by most of the units, but white is favoured by the Light Infantry and red and yellow by the Royal Anglians. In some cases this reflects parts of the regimental recruiting areas: the Light Infantry is associated with part of Yorkshire (represented by a white rose), the Fusiliers with part of historic Lancashire and the Princess of Wales's area includes Hampshire (both counties having red roses as insignia).
In 1975, August 1 was adopted as Yorkshire Day, partly to reflect the presence of Yorkshire soldiers at the battle.
