thrown at the barges, but it only hit the mark once (causing a little damage to one barge). At 2:00 p.m., the workers poured oil onto the river, hoping the oil slick would burn the barges; attempts to light the slick failed. Calls for state intervention The AA worked behind the scenes to avoid further bloodshed and defuse the tense situation. At 9:00 a.m., outgoing AA international president William Weihe rushed to the sheriff's office and asked McCleary to convey a request to Frick to meet. McCleary did so, but Frick refused. He knew that the more chaotic the situation became, the more likely it was that Governor Robert E. Pattison would call out the state militia. Sheriff McCleary resisted attempts to call for state intervention until 10 a.m. on July 6. In a telegram to Governor Pattison, he described how his deputies and the Carnegie men had been driven off, and noted that the workers and their supporters actively resisting the landing numbered nearly 5,000. Pattison responded by requiring McCleary to exhaust every effort to restore the peace. McCleary asked again for help at noon, and Pattison responded by asking how many deputies the sheriff had. A third telegram, sent at 3:00 p.m., again elicited a response from the governor exhorting McCleary to raise his own troops. Pinkerton surrender At 4:00 p.m., events at the mill quickly began to wind down. More than 5,000 men—most of them armed mill hands from the nearby South Side, Braddock and Duquesne works—arrived at the Homestead plant. Weihe wanted to prevent further trouble at Homestead, so he pleaded with Frick to confer with representatives of the Amalgamated to return to Homestead and stop the armed conflict. Weihe urged the strikers to let the Pinkertons surrender, but he was shouted down. Weihe tried to speak again, but this time his pleas were drowned out as the strikers bombarded the barges with fireworks left over from the recent Independence Day celebration. Hugh O'Donnell, a heater in the plant and head of the union's strike committee, then spoke to the crowd. He demanded that each Pinkerton be charged with murder, forced to turn over his arms and then be removed from the town. The crowd shouted their approval. The Pinkertons, too, wished to surrender. At 5:00 p.m., they raised a white flag and two agents asked to speak with the strikers. O'Donnell guaranteed them safe passage
