Etheridge joined as a laundress when her husband enlisted in the 2nd Michigan Infantry Regiment. She later served as the daughter of the
3rd Michigan Infantry Regiment. Though her husband soon deserted, Etheridge served throughout the rest of the war with the
5th Michigan Infantry. When the regiment went on campaign, the other laundresses went home, but Etheridge stayed with the regiment. She was described as young, attractive, modest, quiet, and hard-working. Supposedly, if anyone treated her with disrespect, they would have to fight the entire regiment. After General
Philip Kearny saw her caring for wounded men during the
Peninsula campaign, he "adopted" her into his
III Corps division. He provided her with a horse, saddle, and
sergeant's pay, while her nominal title was cook for the officers mess. She typically wore a black riding habit with sergeant's chevrons. Etheridge was famous for her courageous work under fire, her skirt often being torn by bullets. Armed with pistols for her protection and saddlebags filled with medical supplies, Etheridge frequently rode into the front lines on horseback to aid wounded soldiers. Etheridge embodied the ideal daughter of the Union, much unlike her husband. She was "brave, constant, tender possessed nerves of steel, and willing to join the fight as necessary, encourage[d] the men to greater valor, or remain[ed] in the rear treating wounds." Etheridge was repeatedly exposed to the same hardships as the soldiers she treated, such as sleeping on the ground in camp. The death of her father gave her the longing to save every soldier. Various accounts locate Etheridge at notable battles, such as the
First Bull Run,
Williamsburg,
Second Bull Run,
Antietam,
Fredericksburg, and
Gettysburg. Etheridge was in every battle of the
Army of the Potomac except the
Battle of South Mountain. At the
Battle of Chancellorsville on the morning of May 3, 1863, Etheridge rode up to a general and his staff with a sack of
hardtack and a dozen canteens filled with hot coffee. The men tried to get her to leave but she insisted on remaining until each of the officers ate and drank. During the time she waited, three horses were hit by Confederate
solid shot. Yet, as a nearby soldier wrote, "she never flinched or betrayed the slightest emotion of fear". Later, she appeared at a Union
artillery battery that had taken serious casualties in men, horses, and equipment. The artillerists were considering leaving the guns, but she talked them out of it, offering the soldiers encouragement. The gunners cheered, insisted that she leave, and returned to their duties. One soldier noted "that brave little sergeant in petticoats" bucked up their morale more than any officer could have done. In 1864, all women were ordered out of camp as a result of an order from General Ulysses S. Grant. As a testimony to Etheridge's admirable service, numerous officers signed a petition addressed to General Grant to allow Etheridge to remain in service on the field, but it was denied. "Gentle Annie" then worked for the
Hospital Transport Service, a subcommittee of the
U.S. Sanitary Commission. Assigned to the
Knickerbocker, under
Amy M. Bradley, she aided in the transportation of wounded men from the ports of Alexandria, Virginia, to Philadelphia, New York City, and Washington. For her work and courage, she received the Kearny Cross. == After the war ==
