National Guardsmen with live ammunition and orders to shoot if necessary stood by yesterday in Augusta. Ga., in the wake of racial violence that has left six black men dead.

After looting and sniper fire reportedly began. Governor Lester Maddox ordered National Guardsmen and state police into the city.

By Tuesday morning, six black men had died of gunshot wounds and 60 other people had been injured.

Black unrest in the city began after a 16-year-old black prisoner. CharlesOatman, was beaten to death in jail. Police claimed that other prisoners had done the beating. but local blacks said that sheriff's officers had beaten Oatman.

Yesterday, Sheriff E. R. Atkins charged two black cellmates with murder in the fatal beating of Oatman.

"Those sniping at our Guardsmen-we're not going to ask them to stop." he said "They'd better be prepared to meet their Maker."
