The Battle of Palmito Ranch<span>, also known as the </span>Battle of Palmito Hill<span>, is generally recognized as the final battle of the </span>American Civil War<span>. It was fought May 12 and 13, 1865, on the banks of the </span>Rio Grande<span> east of </span>Brownsville, Texas<span> and a few miles from the seaport of Los Brazos de Santiago, more than a month after </span>Robert E. Lee<span> had surrendered to </span>Ulysses S. Grant<span>in the </span>Eastern Theater<span>. Though the </span>Battle of Appomattox Court House<span> is identified as the last </span>major<span> battle of the war, Palmito Ranch was the last engagement between organized forces of the </span>Union Army<span> and </span>Confederate States Army<span> involving casualties Hope this helps!
