The Flag of His Country is a 1910 American silent short drama film produced by the Thanhouser Company. The patriotic film focuses on a man aptly named Walter North who sides with the Union in the American Civil War, while his wife sides with the Confederacy.

Little is known about the production and cast of the film, but the role of granddaughter was played by Marie Eline. Released on July 1, 1910, the film took place within living memory of the war and a reviewer in The Moving Picture World noted that the film would not offend its audience members.

Plot

Though the film is presumed lost, a synopsis survives in The Moving Picture World from July 2, 1910. It states: "Walter North is a New York man, married to a Southern girl. At the opening of the play their baby daughter is christened, and the young couple is living happily in their home in Baltimore. This is in 1861, the opening of the Civil War. At the first rumors of hostilities, Mrs. North's brother enlisted in the ranks of the Confederacy. When North refuses to follow his example, and casts his lot with the Union army, his wife bids him good-bye forever. She asked him to choose between his flag and her. He salutes Old Glory, and goes to war. Four years later when he returns he finds his old home deserted, and although he tries in every way to discover the whereabouts of his wife and child he is unsuccessful. He moves to a northern home and there becomes commander of a Grand Army of the Republic post. Mrs. North, who believed that her husband was killed in the war, comes North with her brother and her little grandchild to attend the reunion of the Confederate veterans and the Grand Army of the Republic. While out working with her grandmother, the little girl is lost, and is picked up by North on his way to attend the reunion. Through the police the grandmother and uncle are notified of the whereabouts of the child, and when they come to claim her at the Grand Army of the Republic post, there are mutual recognitions, and Mr. and Mrs. North are reunited. There is but one flag now, the blue and the gray clasp hands beneath its folds."
