[citation needed] On 8 October 1967 when the guerrillas' final battle commenced in the Yuro Ravine, Willy was leading the "center" group as they tried to find a way to break out of the Army's encirclement.

Willy was just at the point of clearing the steep wall of the ravine when Guevara, following some distance behind him, received a sudden blast of machine gun fire that wounded him in the leg.

[3] However, the two guerrillas almost immediately found themselves surrounded by another group of rangers who opened fire against them; Guevara and Willy shot back at them until one of their bullets knocked Che's beret off his head and another disabled his M-2 carbine.

"[citation needed] The rangers took Guevara and Willy to the nearby village of La Higuera where they were imprisoned overnight in separate rooms of a small adobe schoolhouse.

The next day, after the order issued by Bolivian President René Barrientos that they should both be killed had been confirmed, the commanding officer sent an execution squad consisting of three soldiers into the schoolhouse.

Almost thirty years after his death, on 28 June 1997, a Cuban forensic team discovered his skeleton in the same burial pit situated on the auxiliary runway of the Vallegrande airport that contained the remains of Che Guevara and five other guerrillas.
