 Two days before Dr. Boland instructed this audience, on the bloody Sunday of March 7th, Alabama state troopers and Dallas County Sheriff's deputies used clubs, horses, tear and nausea gas, and smoke bombs to drive Negro marchers, beginning their first attempt to march on Montgomery, back across the Pettus Bridge and through the town to the Negro Quarter, clubbing them all the way. The result was 57 injured, 17 of those hospitalized.
