Even Ferdinand, the King of Arragon, was induced to loan his connivance to a plan for robbing a near relative of his crown, by the promise of sharing in the spoil.

A treaty of partition was entered into by the two robber kings, by which Ferdinand of Arragon was to receive Calabria and Apulia, and the King of France the remaining States of the Neapolitan kingdom.

The pope was confidentially informed of this secret plot, which was arranged at Grenada, and promised the plunderers his benediction, in consideration of the abundant reward promised to him.
The doom of the King of Naples was now sealed.

All unconscious that his own relative, Ferdinand of Arragon, was conspiring against him, he appealed to Ferdinand for aid against the King of France.

The perfidious king considered this as quite a providential interposition in his favor.
He affected great zeal for the King of Naples, sent a powerful army into his kingdom, and stationed his troops in the important fortresses.
