Returning South, she visited all points on the river down to New Orleans, coming back to make her home for the time at Vicksburg, as the place nearest the centre of her field of labor. The Superintendent and Matrons of the Soldiers' Home extended to her a hearty welcome, happy to have their institution honored by her presence, and receive her sympathizing and kindly aid. So substantial was the reputation she had won among the army, that her presence alone, at a military post in the West, was a power for good. Officers and attendants in charge of hospitals knew how quick she was to apprehend and bring to light any delinquency in the performance of their duties, and profited by this knowledge to the mutual advantage of themselves and those thrown upon their care.
During the summer of 1864, the garrison of Vicksburg suffered much from diseases incident to the season in that latitude. Perhaps in no regiment was the mortality greater than in the Second Wisconsin Cavalry. Strong men sickened and died within a few days, and others lingered on for weeks, wasting by degrees, till only skin and bone were left. The survivors, in evidence of their appreciation of her sympathy and exertions for them in their need, presented her an elegant enameled gold watch, beautifully set with diamonds. The presentation was an occasion on which she could not well avoid a public appearance, and those who were present, must have wondered that one of such power in private conversation should have so little control, even of her own feelings, before an assembly. Mrs. Harvey has never distinguished herself as a _public_ speaker. Resolute, impetuous, confident to a degree bordering on the imperious, with power of denunciation to equip an orator, she yet shrinks from the gaze of a multitude with a woman's modesty, and the humility of a child. She does not underestimate the worth of true womanhood by attempting to act a distinctively manly part.
Although known as the agent of the State of Wisconsin, Mrs. Harvey has paid little regard to state lines, and has done a truly national work. Throughout the time of her stay with the army, applications for her aid came as often from the soldiers of other states as from those of her own, and no one was ever refused relief if to obtain it was in her power. Acting in the character of a friend to every Union soldier, from whatever state, she has had the entire confidence of the great Sanitary Commissions, and rendered to their agents invaluable aid in the distribution of goods. The success that has everywhere attended Mrs. Harvey's efforts, directly or indirectly, to benefit the soldier, has given to her life an unusual charm, and established for her a national reputation.
