6 December 1917 is a day indelibly etched in the hearts and minds of the citizens of Halifax and Dartmouth, Nova Scotia. On that Thursday the Norwegian vessel SS Imo, carrying Belgian relief supplies, and the French freighter SS Mont Blanc, carrying munitions, collided in Halifax Harbour, thereby creating what was then considered to be the worst man-made disaster in the world's history.
Correspondence, notes, reports, press clippings, and personal narratives detailing events of the disaster, including damages, injuries, and medical and relief activities. Much of the material was used in Archibald MacMechan's history of the Halifax Explosion, 6 December 1917.
