The NAACP sent a telegram of protest to President Woodrow Wilson: The shame put upon the country by the mobs, including United States soldiers, sailors, and marines, which have assaulted innocent and unoffending negroes in the national capital. Men in uniform have attacked negroes on the streets and pulled them from streetcars to beat them. Crowds are reported ...to have directed attacks against any passing negro.… The effect of such riots in the national capital upon race antagonism will be to increase bitterness and danger of outbreaks elsewhere. National Association for the Advancement of Colored People calls upon you as President and Commander in Chief of the Armed Forces of the nation to make statement condemning mob violence and to enforce such military law as situation demands.…

Longstanding racial tensions between whites and blacks exploded in five days of violence that started on July 27, 1919. On that hot summer day, on a segregated Chicago beach, a group of white men stoned Eugene Williams to death when he crossed the unofficial barrier between the white and black sections of the 29th Street beach. Tensions escalated when a white police officer not only failed to arrest the white man responsible for Williams' death, but arrested a black man instead. Objections by black observers were met with violence by whites. Attacks between white and black mobs erupted swiftly. Because of the rioting, 38 people died (23 African American and 15 white), and another 537 were injured, two-thirds of them African American; one African-American Patrolman John W. Simpson was the only policeman killed in the riot.

On the night of 29–30 July, the Romanian Army crossed the Tisza River. Decoy operations were mounted at other points along the river, bringing intense artillery duels. Romanian forces held the element of surprise.
