The improvement in the work of the deputies had such a marked effect that, in the third week of September, the Fifteenth regiment was ordered home, and, on the last day of the month four companies of the Sixteenth regiment broke camp, leaving but four companies on the ground, one of which was posted on the hillside across the river from Homestead. Two weeks later, on October 13, the last of the militia received orders to leave, the first intimation of the good news being conveyed to the men when the band struck up "Home, Sweet Home" at the morning reveille. Tents were struck and baggage packed in short order, and at 10 A. M. the last vestige of the encampment was removed, and with a cheer that re-echoed among the hills the boys in blue marched to Munhall Station and were soon on the way to their homes in the oil country. The Homesteaders watched the departure without showing much feeling, although many of them, doubtless, experienced a consciousness of relief now that, after ninety-five days of military surveillance, the town was restored to the hands of the civil authorities. Henceforward the preservation of the peace was exclusively in the hands of the sheriff's deputies, thirty in number. An outrage which caused considerable indignation about this time was the attempt made by unknown desperadoes to blow up the Mansion House, a hotel situated at the corner of Fifth avenue and Amity street, in the most populous quarter of Homestead. The establishment was conducted by Mrs. Marron, a widow who had been induced to come from Pittsburgh in order to provide boarding for employees of the Carnegie firm. She secured 40 boarders from among the clerks and non-union steelworkers employed in the mill. On the night of October 6, when the occupants of the hotel were sleeping, an explosive of some kind was thrown through a window of the dining-room on the ground floor. The missile exploded with great force, tore a hole through the floor and penetrated the cellar. Beyond the wrecking of an empty room, however, no damage was done. Mrs. Marron naturally laid the blame for the occurrence on the strikers, but they stoutly disclaimed responsibility and contended that the damage had been done by a natural gas explosion and not by a bomb thrown with intent to kill and destroy. Another theory which found favor among the men was that some wily foe to organized labor had done the mischief in order to discredit the cause of the strikers and hasten the end of the strike by altering the drift of public sympathy. Mr. Frick offered $1,000 for the arrest of the supposed dynamiter and $100 additional was offered by the advisory committee, but the reward was never earned.
