A soldier with The Royal Inniskilling Fusiliers, he was posthumously awarded the VC for his actions on 29 September 1918, during the Hundred Days Offensive of the First World War.

[1] On the outbreak of the First World War, Seaman returned to the United Kingdom and tried to enlist in the British Army.

As the war progressed, the high casualty rates in the British Expeditionary Force saw standards for frontline service lowered and Seaman was transferred to an infantry unit, the 2nd Battalion of The Royal Inniskilling Fusiliers.

Serving in the Ypres salient, he was soon awarded the Military Medal (MM) for attending, while under fire, to fellow soldiers who had been wounded.

Seaman, a lance corporal operating a Lewis gun, played a key role in getting the advance restarted although he was killed in the process.

King George V presented Seaman's VC to his mother in a ceremony at Buckingham Palace on 13 February 1919.
