James Samuel Wadsworth was a philanthropist, politician, and a Union general in the American Civil War. He was mortally wounded at the Battle of the Wilderness in 1864.

The Battle of the Wilderness was fought on May 5–7, 1864, during the American Civil War. It was the first battle of Lieutenant General Ulysses S. Grant's 1864 Virginia Overland Campaign against General Robert E. Lee and the Confederate Army of Northern Virginia. The fighting occurred in a wooded area near Locust Grove, Virginia, about 20 miles (32 km) west of Fredericksburg. Both armies suffered heavy casualties, nearly 29,000 in total, a harbinger of a war of attrition by Grant against Lee's army and, eventually, the Confederate capital, Richmond, Virginia. The battle was tactically inconclusive, as Grant disengaged and continued his offensive.
