The Battle of Modder River was an engagement in the Boer War, fought at Modder River, on 28 November 1899. A British column under Lord Methuen, that was attempting to relieve the besieged town of Kimberley, forced Boers under General Piet Cronjé to retreat to Magersfontein, but suffered heavy casualties altogether.

The Grenadier Guards is the most senior infantry regiment of the British Army, being at the top of the Infantry Order of Precedence. It can trace its lineage back to 1656 when Lord Wentworth's Regiment was raised in Bruges to protect the exiled Charles II. In 1665, this regiment was combined with John Russell's Regiment of Guards to form the current regiment, known as the 1st Regiment of Foot Guards. Since then, the regiment has filled both a ceremonial and protective role as well as an operational one. In 1900, the regiment provided a cadre of personnel to form the Irish Guards; while later, in 1915 it also provided the basis of the Welsh Guards upon their formation.
