He approached the Spanish Minister first through one of his fellow conspirators and then in his own person.

At one time he made his request on the pretence that he wished to desert the other filibusterers, and save Spain by committing a double treachery, and betraying the treasonable movement into which he had entered; and again he asked funds on the ground that all he wished to do was to establish a separate government in the West, and thus destroy the power of the United States to molest Spain.

However, his efforts came to naught, and he was obliged to try what he could do unaided in the West.

His first stop of importance was at Blennerhassett's.

Blennerhassett was the one person of any importance who took his schemes so seriously as to be willing to stake his fortune on their success.
