Adjutant General [[Charles F. Barrett]] of the Oklahoma National Guard arrived by special train at about 9:15&nbsp;a.m., with 109 troops from Oklahoma City. Ordered in by the governor, he could not legally act until he had contacted all the appropriate local authorities, including Mayor [[T. D. Evans]], the sheriff, and the police chief. Meanwhile, his troops paused to eat breakfast. Barrett summoned reinforcements from several other Oklahoma cities. Barrett declared [[martial law]] at 11:49&nbsp;a.m.,{{sfn|Hirsch|2002|p=107}} and by noon the troops had managed to suppress most of the remaining violence.

Thousands of black residents had fled the city; another 4,000 people had been rounded up and detained at various centers. Under martial law, the detainees were required to carry identification cards.{{sfn|Oklahoma Commission|2001|pp=123–132}} As many as 6,000 Greenwood residents were interned at three local facilities: Convention Hall (now known as the [[Tulsa Theater]]), the [[Tulsa State Fair|Tulsa County Fairgrounds]] (then located about a mile northeast of Greenwood) and McNulty Park (a baseball stadium at Tenth Street and Elgin Avenue).<ref name="messerbell">{{cite journal |last1=Messer |first1=Chris M. |last2=Bell |first2=Patricia A. |title=Mass Media and Governmental Framing of Riots |journal=Journal of Black Studies |date=July 31, 2008 |volume=40 |issue=5 |pages=851–870 |doi=10.1177/0021934708318607 |jstor=40648610 |s2cid=146678313 }}</ref><ref name=mcnulty>{{Cite news |url=https://tulsaraceriot.wordpress.com/2013/03/06/mcnulty-park/ |title=McNulty Park |date=March 6, 2013 |work=The Tulsa Race Riot of 1921 |access-date=November 3, 2018 |language=en-US |archive-url=https://web.archive.org/web/20181103092217/https://tulsaraceriot.wordpress.com/2013/03/06/mcnulty-park/ |archive-date=November 3, 2018 |url-status=live }}</ref>{{sfn|Oklahoma Commission|2001|pp=83, 177}}

A 1921 letter from an officer of the Service Company, Third Infantry, Oklahoma National Guard, who arrived on May 31, 1921, reported numerous events related to the suppression of the riot:
* taking about 30–40 black residents into custody;
* putting a machine gun on a truck and taking it on patrol, although it was not functioning and much less useful than "an ordinary rifle";
* being fired on by black snipers from the "church" and returning fire;
* being fired on by white men;
* turning the prisoners over to deputies to take them to police headquarters;
* being fired upon again by armed black residents and having two [[Non-commissioned officer|NCOs]] slightly wounded;
* searching for black snipers and firearms;
* detailing an NCO to take 170 black residents to the civil authorities; and
* delivering an additional 150 black residents to the Convention Hall.<ref name="Voorhis letter">{{cite web |url=https://digitalprairie.ok.gov/digital/collection/race-riot/id/265 |title=Letter Captain Frank Van Voorhis to Lieut.

Captain John W. McCune reported that stockpiled ammunition within the burning structures began to explode, which might have further contributed to casualties.<ref>{{cite web |title=Letter Chas F.
