In this failed operation his father Román commandant of the expeditionary was killed, leading Carlos to return to France.

Delgado Chalbaud spent most of his life in Paris, where he studied engineering and later attended the Saint-Cyr military academy.

He returned to Venezuela in 1939 and was promptly commissioned in the Venezuelan army by president General Eleazar Lopez Contreras with the rank of captain.

His murder seems to be the unintended outcome of a failed kidnapping led by Simón Urbina, who looked to overthrow the Chalbaud presidency.

[citation needed] Cerro Carlos Delgado Chalbaud (1047m), a mountain in Venezuela's Amazonas estate where the headwaters of the Orinoco River are located, is named after him.
