Although the drawings did not get much attention at the time, they mark Homer's expanding skills from illustrator to painter. Like with his urban scenes, Homer also illustrated women during wartime, and showed the effects of the war on the home front. The war work was dangerous and exhausting. Back at his studio, Homer would regain his strength and re-focus his artistic vision. He set to work on a series of war-related paintings based on his sketches, among them Sharpshooter on Picket Duty (1862), Home, Sweet Home (1863), and Prisoners from the Front (1866). He exhibited paintings of these subjects every year at the National Academy of Design from 1863 to 1866. Home, Sweet Home was shown at the National Academy to particular critical acclaim; it was quickly sold and the artist was consequently elected an Associate Academician, then a full Academician in 1865. During this time, he also continued to sell his illustrations to periodicals such as Our Young Folks and Frank Leslie's Chimney Corner.
Homer spent two years (1881–1882) in the English coastal village of Cullercoats, Tyne and Wear. Many of the paintings at Cullercoats took as their subjects working men and women and their daily heroism, imbued with a solidity and sobriety which was new to Homer's art, presaging the direction of his future work. He wrote, "The women are the working bees. Stout hardy creatures." His works from this period are almost exclusively watercolors. His palette became constrained and sober; his paintings larger, more ambitious, and more deliberately conceived and executed. His subjects more universal and less nationalistic, more heroic by virtue of his unsentimental rendering. Although he moved away from the spontaneity and bright innocence of the American paintings of the 1860s and 1870s, Homer found a new style and vision which carried his talent into new realms.
