A Civil War camp scene painted by Winslow Homer – who captured war’s fury at the front and documented soldiers’ lives behind the lines – will debut Sunday as part of the relaunch of an American art gallery at a Southern California museum.

Homer (below) was in his mid-20s when he became an artist-reporter for Harper’s Weekly, embedding with the Union army in Virginia. While most of his work about the conflict was illustrations, he did produce several paintings, including “The Sutler’s Tent,” which was acquired by The Huntington.

The San Marino, Calif., institution recently announced the acquisition of the work, which was purchased for an undisclosed amount from a New York-based gallery. The Ahmanson Foundation funded the acquisition in honor of the 250^th anniversary of the founding of the United States, officials said.

The 1863 painting, only 16-1/4 inches by 12 inches, shows two Yankee cavalry troopers near a tent, one munching on what appears to be a slice of pie (another theory it is bread and cheese).

The blog Los Angeles County Museum on Fire points out the celebrated artist first depicted the subject in an 1862 sketch, which shows more than a half dozen members of the 3^rd Pennsylvania Cavalry standing near a tent. One of them is sitting on a rail, enjoying a snack.

The drawing was modified for publication in Harper’s Weekly and entitled "Thanksgiving in Camp."

“Harper's Weekly reproduced Homer's war art as wood engravings. ‘The Sutler's Tent’ is related to a Thanksgiving-themed illustration that ran in November 1862,” according to William Poundstone’s blog. “That means the engraving came before the painting, dated 1863. The horizontal-format print shows many more figures than the painting and clearly shows the tent. … Homer evidently felt the tight cropping of the painting made a stronger composition.”

Homer honed his craft during the Civil War. A 2015 article in Yale News describes how the self-taught artist had to work quickly and be an astute observer. The young man grew a beard like many soldiers and also wore worn and dirty clothing.

“Homer, like other war correspondents, considered what he did to be a public service and felt as though he endured some of the same kind of experiences as soldiers did,” Keely Orgeman, a curator with the Yale University Art Gallery, told the publication. “When Homer was stationed in Yorktown on the front, he was unable to eat for three days, along with all of the soldiers. According to his mother, he was completely changed by that experience.”

Homer’s other well-known Civil War works include “Prisoners from the Front,” “Home, Sweet Home” and “A Sharp Shooter on Picket Duty.”

Homer's "Prisoners from the Front" is owned by the Metropolitan Museum of Art and displayed in New York.

The purchase of “The Sutler’s Tent” was first reported by the Los Angeles Times.

Annabel Adams, vice president of communications and marketing for The Huntington, told the Picket the reasoning for acquiring the museum’s first Homer painting (it does have sketches) was “especially important as we set to launch a reinstallation of American art galleries on December 7 as part of our ‘This Land Is’ initiative.”

The multiyear effort includes the reinstallation of seven galleries in the Virginia Steele Scott Galleries of American Art.” One reopened in September; six will debut Sunday.

As Poundstone reported, “The Sutler’s Tent” will be the centerpiece of a room about the Civil War and Reconstruction. On display will be a signed copy of the Emancipation Proclamation from The Huntington’s Library and Jean-Baptiste Carpeaux’s scultpure "Why Born Enslaved!," The Huntington said in a news release.

Adams said the institution’s Civil War holdings are renowned. Among them:

-- Papers relating to President Abraham Lincoln’s bodyguard Ward Hill Lamon;

-- Ciphered communications between Abraham Lincoln and army commanders;

-- Lincoln memorabilia and manuscript collector Judd Stewart;

-- Scrapbooks made by war correspondent and illustrator James E. Taylor (left, courtesy The Huntington);

-- Alfred R. Waud’s 1863 drawing of Rebel prisoners at Brandy Station.

Christina Nielson, the Hannah and Russel Kully Director of the Art Museum at The Huntington, said “Sutler’s Tent” expands the dialogue between the art and library collections.

“As we look toward the 250th anniversary of the United States, the painting invites reflection on a pivotal chapter in our nation’s history -- one that continues to shape the American experience,” she said in the news release.

The Huntington also features botanical gardens and a research center.
