Editing Tulsa race massacre (section)

===Daybreak===
Upon sunrise, around 5 a.m., a train whistle sounded (Hirsch said it was a siren). Some rioters believed this sound to be a signal for the rioters to launch an all-out assault on Greenwood. A white man stepped out from behind the Frisco depot and was fatally shot by a sniper in Greenwood. Crowds of rioters poured from their shelter, on foot, and by car, into the streets of the neighborhood. Five white men in a car led the charge but were killed by a fusillade of gunfire before they had traveled one block.{{sfn|Hirsch|2002|pp=98–99}}

Overwhelmed by the sheer number of attackers, black residents retreated north on Greenwood Avenue to the edge of town. Chaos ensued as terrified residents fled. The rioters shot indiscriminately and killed many along the way. Splitting into small groups, they began breaking into houses and buildings, looting. Several residents later testified the rioters broke into occupied homes and ordered the residents out to the street, where they could be driven or forced to walk to detention centers.{{sfn|Hirsch|2002|pp=97–105, 108}} A rumor spread among the rioters that the new [[Mount Zion Baptist Church (Tulsa)|Mount Zion Baptist Church]] was being used as a fortress and armory. Purportedly twenty caskets full of rifles had been delivered to the church, though no evidence was found.{{sfn|Hirsch|2002|p=107}}
