Ronald Liversedge’s Mac-Pap: Memoirs of a Canadian in The Spanish Civil War provides a fascinating and much needed contribution to the slowly growing number of books on Canada’s role in the Spanish Civil War. Liversedge’s memoir traces his actions at Fuentes de Ebro, his time with the Canadian Cadre Service, his service with the 35th Artillery Battalion, and his eventual repatriation to Canada in 1939. An honest depiction of a prominent member of the International Brigades, this book is a must-read for anyone interested in North American participation in the Spanish Civil War.
