After waiting some time for an opportunity to go she wrote to Mr. James E. Yeatman, at St. Louis, the agent of Miss Dorothea L. Dix for the appointment of women nurses in the hospitals of the Western Department, and was accepted. On reporting herself at St. Louis she was commissioned as a nurse, and in the fall of 1862 proceeded to Helena, where the army of the Southwest had encamped the previous July, under Major-General Curtis, and where every church and several private buildings had to be converted into hospitals to accommodate the sick of his army.
It was here, during the winter of 1863, that the writer of this sketch first met with Miss Maertz, engaged in the work of a hospital nurse, enduring with rare heroism sacrifices and discomforts, labors and watchings in the service of the sick soldiers that won the reverence and admiration of all who saw this gentle woman thus nobly employed. It was of her the following paragraph was written in the History of the Western Sanitary Commission.
"Another one we also know whose name is likewise in this simple record, who, at Helena, Arkansas, in the fall and winter of 1862-3, was almost the only female nurse in the hospitals there, going from one building to another, in which the sick were quartered, when the streets were almost impassable with mud, administering sanitary stores and making delicate preparations of food, spending her own money in procuring milk and other articles that were scarce and difficult to obtain, and doing an amount of work which few persons could sustain, living without the pleasant society to which she had been accustomed at home, never murmuring, always cheerful and kind, preserving in the midst of a military camp such gentleness, strength and purity of character that all rudeness of speech ceased in her presence, and as she went from room to room she was received with silent benedictions, or an audible 'God bless you, dear lady,' from some poor sufferer's heart."
The last time I saw Miss Maertz, while engaged in her hospital work, was at the grave of a soldier, who was buried at Helena in the spring of 1863. He was one of the persecuted Union men of Arkansas, who had enlisted in the Union army on the march of General Curtis through Arkansas, and had fallen sick at Helena. For several weeks Miss Maertz had nursed and cared for him with all a woman's tenderness and delicacy, and perceiving that he must die had succeeded in sending a message to his wife, who lived sixty miles in the interior of Arkansas, within the enemy's lines. On the afternoon of his death and but a few hours before it she arrived, having walked the whole distance on foot with great difficulty, because she was partially blind; but had the satisfaction of receiving the parting words of her husband and attending his burial. Miss Maertz sent word to me, asking me to perform the burial service, and the next day I met her leading the half-blind widow, in her poverty and sorrow, to the grave. Some months later this poor soldier's widow came to the Refugee Home, at St. Louis, and was cared for, and being recognized and the scene of the lonely burial referred to, she related with tears of gratitude the kindness she received from the good lady, who nursed her husband in his last illness at Helena.
At a later period in the service, Miss Maertz was transferred to the hospitals at Vicksburg, where she continued her work of benevolence till she was obliged to return home to restore her own exhausted energies. At this time her parents urged her to go with them to Europe, wishing to take her away from scenes of suffering, and prostrating disease, but she declined to go, and, on regaining a measure of health, entered the service again and continued in it at New Orleans to the end of the war.
In real devotion to the welfare of the soldiers of the Union; in high religious and patriotic motives; in the self-sacrificing spirit with which she performed her labors; in the heroism with which she endured hardship for the sake of doing good; in the readiness with which she gave up her own interests and the offer of personal advantages and pleasure to serve the cause of patriotism and humanity, she had few equals.
