Celebrated in song by Christy Moore and affectionately recalled in many memoirs, Robert "Bob" Hilliard, the author's grandfather, is one of Ireland's best-known International Brigadistas. His short life blazed with a rare intensity; his death in Spain left a dark shadow hanging over his family. This book unravels Hilliard’s enigmas to bring us an absorbing character and a fresh understanding of the times that shaped him. Hilliard was radicalised at school by the Irish revolution. Variously a journalist, an Olympic boxer for Ireland and a Church of Ireland priest, he became a communist and anti-fascist in London, fought with the International Brigades in the Spanish Civil War and died of wounds sustained at the Battle of Jarama. Eloquent and colourful, he inspires puzzlement as well as admiration. Why was his life so full of contradictions? One question haunted the author's mother: how could he leave his children? Lin Rose Clark sets out to find answers. Through meticulous research and a deeply personal exploration of her family's past, she brings together an engrossing picture of the man and a tale of flawed romance, passionate commitment and war, portraying Hilliard as part of a turbulent history that still reverberates today.
