On the morning of December 6, 1917, the residents of Halifax's North End witnessed first hand the terrifying destruction of the First World War when a fully loaded munitions ship collided with a larger relief ship, caught fire and then exploded in the harbour. The blast laid waste a huge residential area as well as the waterfront and several factories. This book offers a definitive account of the explosion and its aftermath, and the most extensive collection of images, many in colour, available in print.
