An interesting quote from the CIA Intelligence Report dated 23 March 1948 stated 'The reported refusal of Mora's PVP forces to march against Figueres' forces has given rise to serious differences among PVP and Government military leaders. Mora has stated hat he will use his men to defend his party. As an example of the PVP's lukewarm attitude toward combat duty and their careful guarding of arms already in their possession, the experience of Governemnt military leader Col. Diego Lopez is cited. An order by Col. Lopez on 17 March to the PVP to supply a contingent of armed men resulted in ten militants reporting for duty without rifles or ammunition. The men were ordered to return to CTCR headquarters and to come back with arms. They left but did not bother to return.'
