Lucy's first husband came into the Union lines as a laborer under General Grant, or may have possibly served in a colored regiment that was formed; but it is not known what happened to him. Mona, Lucy's young daughter, died at the Siege of Vicksburg. Although the details of her death are not known, the Indiana 23rd Infantry offered her a funeral with flowers. In the middle of the war, when the regiment went on furlough to New Albany, Indiana, Lucy went with them and was employed as a servant by several officers, including General W. Q. Gresham. When the Indiana 23rd Infantry were re-deployed to the war in Mississippi, she returned to her nursing duties in service of the Union and was present at every siege. Lucy followed the army east under General Sherman, in The March to the Sea, and then north, where the 23rd Infantry was present in the Grand Review of the Armies.
