[6] After the outbreak of the Second Boer War, Lord Wolverton volunteered for active service and joined the Imperial Yeomanry.

He left Southampton on board the SS Scot in late January 1900,[7] and arrived in South Africa the following month.

[8] He was appointed Honorary Colonel of the 2nd (South Middlesex) Volunteer Rifle Corps on 29 August 1903, and when the unit was merged into the 13th (Kensington) Battalion, London Regiment, in the new Territorial Force in 1908, Wolverton helped to set up a new 10th Battalion, Middlesex Regiment, and became Hon Colonel of that unit.

[9][10] Lord Wolverton married Lady Edith Amelia, daughter of William Ward, 1st Earl of Dudley, in 1895.

They had four children: Lord Wolverton died in October 1932, aged 68, and was succeeded in the barony by his second but eldest surviving son, Nigel.
