By all accounts, Saturday, July 19, 1919 was a hot, muggy night in Washington, D.C. The stifling heat probably didn’t help the disposition of patrons in the city’s saloons which, in this era of early-Prohibition, could only offer the tamest of liquid refreshments. (Though, undoubtedly many barflies acquired stiffer drinks at one of the city’s many speakeasies.) It probably didn’t help matters, either, that many of the soldiers and sailors who had recently returned home from the battlefields of World War I were struggling to find work.
