They repeat the process in other towns until Blondie grows weary of Tuco's complaints and strands him in the desert. Bent on revenge, and after one failed attempt with his gang, Tuco finally catches up with Blondie and force-marches him across the desert until Blondie collapses from dehydration. A runaway horse-drawn hospital ambulance arrives with several dead Confederate soldiers and a near-death Bill Carson, who promises Tuco $200,000 in Confederate gold, buried in a grave in Sad Hill Cemetery, in exchange for help. When Tuco returns with water, Carson has died and Blondie slumped next to him, revealing that Carson recovered and told him the name on the grave before dying.
