Mike Chappell comes from an Aldershot family with British Army connections stretching back several generations. He enlisted as a teenage private in the Royal Hampshire Regiment in 1952 and retired in 1974, as RSM of the 1st Battalion The Wessex Regiment (Rifle Volunteers). He began painting military subjects in 1968 and since then has gained worldwide popularity as a military illustrator. Mike has also written and illustrated many books in the Osprey Military list.

The forces which Wellington led in Portugal and Spain and up into southern France between 1808 and 1814 achieved a consistent record of victory perhaps unmatched in the history of the British Army. Some 40 per cent of this volunteer army were Irishmen - a remarkable figure, given the recent unrest and bloodshed in Ireland. This book details the record, and illustrates the uniforms and equipment, of the two cavalry and three infantry units boasting formal Irish identity: the 4th (Royal Irish) Dragoon Guards, 18th Hussars, 27th (Enniskillen), 87th (Prince of Wales's Own Irish), and 88th (Connaught Rangers) Regiments of Foot.
