Unlike most of the gamblers and roughs, who for the most part sympathized with the Confederates, Pinkham was an intense Union man. He never lost an opportunity to proclaim his attachment for the Union cause, and denounced as traitors all who opposed it. No fear of personal injury restrained him in the utterance of his patriotic sentiments, and as he always avowed a readiness to fight for them, his opponents were careful to afford him no opportunity. At every election in Idaho City after the organization of the Territory, he was found at the polls surrounded by a set of plucky fellows armed to the teeth, ready at his command for any violent collisions with secessionists that the occasion might arouse. His tall form, rendered more conspicuous by the loud and inspiring voice with which, to the cries of “negro worshippers,” “abolitionists,” and “Lincoln hirelings,” he shouted back “secessionists,” “copperheads,” “rebels,” and “traitors,” was always the centre of a circle of men who would oppose force to force and return shot for shot. On his return to Idaho City from a business visit to the States, a few days before the anniversary of our national independence of the year in which he was killed, he was so indignant that no preparations had been made for a celebration, that when the day arrived he procured a National flag, hired a drummer and fifer, and followed them, waving the banner, through the streets of the town, greatly to the disgust of the secessionists. The South had just been conquered, and the demonstration wore the appearance of exultation, but no one aggrieved by it had the hardihood to interrupt its progress. “Old Pink,” as he was familiarly called, was much too dangerous a character to meddle with. With all his rough and desperate characteristics, Pinkham had no sympathy for the robbers and murderers and thieves that swarmed around him; and when Idaho was organized the governor of the Territory appointed him sheriff of Boise County. Soon afterwards he received the appointment of United States marshal, an office which made him and his friends in some measure the representatives of law and order. By promptly discharging the duties of these offices, he was held in great fear by the criminal population of the Territory, and won the respect of the best citizens for his efficiency and fidelity.
