Plymouth Blitz recounts the deadliest civilian incident in Plymouth during the Second World War, when a German bomb struck the Portland Square Air Raid Shelter. Through eyewitness accounts and archival research, this book captures the courage, fear, and resilience of ordinary people living under the threat of aerial attack.On the night of 22–23 April 1941, as the German Luftwaffe descended on Plymouth, families from Portland Square and Victoria Street sought refuge in the communal air-raid shelter beneath the park at the centre of the square. They went as neighbours, parents, children—ordinary people seeking protection from an unprecedented bombardment. Just after midnight, a bomb tore through one wing of the shelter, killing at least 71 people in the city’s most devastating incident of the war. Despite its scale and human cost, the Portland Square tragedy has never before been explored as a full, integrated account.Plymouth Blitz is a history from the ground up. Using the Cornelius family as a narrative lens and Portland Square as a case study, it traces daily life, decision-making, and loss in a city under attack. Moving from pre-war preparations through the escalating Luftwaffe threat, the catastrophic bombings in March and April 1941, and the immediate aftermath of navigating civilian mass casualty, the book shows how national war policies were lived out at street level. A richly researched and deeply human account, Plymouth Blitz is essential reading for history enthusiasts, students, educators, and anyone seeking to explore the Blitz beyond the headlines.
