In the hours, days, and weeks following the 1906 earthquake and subsequent fires that all but destroyed San Francisco, the United States Army mobilized to provide security, firefighting, and disaster relief. In this Art of War study, Chaplain Erik C. Alfsen examines the shortcomings and strengths of the military actions, closing the gap between civilian and military scholarship on this event. The book concludes with implications for Defense Support to Civil Authorities (DSCA) missions in the modern era.
