WE KNEW OF the daring plan to transfer rebel groups from Oriente to Las Villas.
Individuals and even families who served the country generously and patriotically had been victimized because chiefs or agents imprudently mentioned their names in connection with their services. We therefore ordered the commands to omit real names, even in private conversation when referring to their activities or to data obtained from reliable sources. Even the President of the Republic was to receive his report in this new format. For example: X-3 would signify information which was probably true, delivered by someone who could be trusted, but who had not been in direct contact with the facts; X-4 would be genuinely true information. Through these channels we would be informed of the movements and important concentrations of the enemy.
This system greatly reduced the possibility of the enemy learning our sources of information. It permitted our leaders to know those who might sabotage the military and political plans of the Government from inside or out.
The reports coming from X-3 and X-4 made me certain that the groups of saboteurs directed by Fidel Castro's lieutenants were trying to put into effect a plan to destroy communications (highways, roads, railways, telephone and telegraph) in the entire Province of Las Villas. This plan to cut the Island in two was to be put in operation the second half of December and was to be completed in January.
