Sir Mark Walker VC KCB (24 November 1827-18 July 1902) was born in Gore Port, Finea, County Westmeath in Ireland. He was an Irish recipient of the Victoria Cross, the highest and most prestigious award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces.

During the Crimean War, Walker was a 26 year old lieutenant in the 30th Regiment of Foot (later the East Lancashire Regiment) British Army when the deed for which he was awarded the VC was performed. chea On 5 November 1854 at Inkerman, Crimea, Lieutenant Walker jumped over a wall in the face of two battalions of Russian Infantry which were marching towards it. This act was to encourage the men, by example, to advance against such odds - which they did and succeeded in driving back both battalions.
