This collection reveals details of the Federal Government's plans to militarily intervene in the 1963 March on Washington (codenamed Operation "Steep Hill") in the event the march became disorderly. Army staff communications and memos tracked the plans of the march organizers throughout the summer, and the Office of the Deputy Chief of Staff for Military Operations prepared contingency plans for cooperation with District of Columbia police for controlling the march. The records also include intelligence reports and estimates, congressional correspondence, press articles, and maps planning the route of the march and facilities needed. These records give an insight into the personalities and events at the march on Washington. In addition, there is small quantity of records relating to the plans to intervene in Alabama in 1963 over the issue of school integration.
