The Union captain (Who's Birth name is unknown)Was a Union officer during the later years of the American civil war. He is a drunk and is constantly seen joking around and seemingly incapable of handling the responsibility that is given to him.He befriended Tuco Ramirez and The Man with no Name when troops under his command found the two wandering close to their encampment. He felt that the bloody confrontation his men were involved in against the local Confederate Garrison was a futile waste of both men and supply. He constantly thought of destroying the bridge that his Garrison was assigned to rpotect because th destruction of the bridge would end the local conflict.

Soon after his introduction to the Tuco and Blondie(The Man with no Name)The Union contingent under his command clashed with the Confederate Garrison and the two groups engaged eachother in a charge over Braxton bridge. The Captain was mortally wounded during the fighting and he was brought back to the Union encampment in a hopless state. However blondie indirectly revealed his plan to destroy the Bridge, giving the Captain hope in his dyeing minutes. He begged for the Union medic to keep him alive for as long as possible in hopes that he would witness the bridge's destrcution. The Bridge explodes a few minutes later, the Capatin is moments from death but the site of the Bridges destrcution allows him a little happiness, he sighs with relief, and dies with smile upon his face.

The Union Captain is played by Aldo Giuffrè.
