Roosevelt convened a conference of representatives of government, labor, and management on October 3, 1902. The union considered the mere holding of a meeting to be tantamount to union recognition and took a conciliatory tone. The owners told Roosevelt that strikers had killed over 20 men and that he should use the power of government "to protect the man who wants to work, and his wife and children when at work." With proper protection, the owner said that they would produce enough coal to end the fuel shortage; they refused to enter into any negotiations with the union. The governor sent in the National Guard, who protected the mines and the minority of men still working. Roosevelt attempted to persuade the union to end the strike with a promise that he would create a commission to study the causes of the strike and propose a solution, which Roosevelt promised to support with all of the authority of his office. Mitchell refused and his membership endorsed his decision by a nearly unanimous vote.
