Lieutenant Henry Albert Whiteside
Henry Albert (born Albert Henry) Whiteside was born on 13 December 1892 at Goragh, Mullaglass, County Armagh, the third or fourth of eight children of farmer David Whiteside and his wife Rebecca (nee Kirkpatrick). By 1911 he was living at Goragh and working on the family farm.
Whiteside enlisted in the North Irish Horse between 12 November and 8 December 1909 (No.426 – later Corps of Hussars No.71025). He embarked for France on 20 August 1914 with C Squadron, seeing action in the retreat from Mons and advance to the Aisne.
Much later in the war he applied for a commission and undertook training at an officer cadet battalion in the UK. On 27 March 1918 he was commissioned as a 2nd lieutenant and posted to the 3rd (Reserve) Battalion, Royal Inniskilling Fusiliers.
Later that year he embarked for France, where he was posted to one of the Inniskilling battalions in the field. He saw action in the Advance to Victory offensive in the last months of the war, and in September or October 1918 was wounded, though not seriously.
Whiteside was promoted to lieutenant in 27 September 1919 and soon after relinquished his commission.
