But they needed a shield to hide their helplessness, and this they found in the federal troops, therefore it requires but little reasoning to understand the bad effect on the people, made by the presence of United States troops, equipped for war in time of peace. This ill feeling, mingled with curiosity produced excitement. Excitement invited the presence of the tough and lawless element, which was exactly what the railroad magnates were striving for, as the strikers had no intention of interfering with their trains, and they knew that it was necessary to incite rioting in order to have an excuse for not operating their roads. Their devilish schemes succeeded only too well. A mob composed of the tough and hoodlum element congregated at the Rock Island yards and from Nineteenth to Fortieth Street, overturned box cars and destroyed everything that came in their way. The mob increased until not less than ten thousand people participated in the work of destruction, but be it said to the credit of the _impartial_ press of that city, they announced that no strikers had taken part in the lawlessness. Mayor Hopkins, who went in person to the scene, said that from what he had heard, and what he could see for himself, that no railroad men were implicated in the depredations, and business men whose veracity could not be questioned corroborated his statement. This occurrence was much to be feared by the strikers, as it was not the first time that such means had been employed to turn public sentiment from the side of the workingmen. Realizing this the men did their utmost to prevent it, and by threats and entreaties tried to persuade the mob to desist from the work of destruction, but were successful only for a short time. One of the strikers remarked to an officer at the time: "By Heavens! this won't do, there is not a striker in that crowd; this is done to injure us, and those fellows are not trying to stop it," meaning the troops. The strike had now reached Toledo, Cleveland and Buffalo, and was rapidly spreading east, the entire country was in a whirlpool of excitement, and the strikers were jubilant. The general managers with the combined forces of the federal troops, state militia, and Cleveland and his cabinet could not operate the roads. One simple word from the general managers to Pullman would have been more effective in starting the trains than all the armies and courts in the United States or all the scabs from Canada, but rather than speak that one word, "arbitration," they would bankrupt every system of railroads in the country. On July 5, President Cleveland received by wire the following protest from Gov. Altgeld of Illinois:
