What was going on in Portugal was, as we have already seen, practically a secret to the French in Spain. For the Portuguese Ordenança and the Spanish guerrilleros had done their work of blocking the roads so well, that no accurate information penetrated to Madrid, Valladolid, or Seville from Santarem. It was only at rare intervals, when Foy and other officers cut their way through this ‘fog of war’ that the condition of affairs on the Tagus became known for a moment. The fog descended again when they had passed through on their way to Paris, and given their information as to the fortunes of the Army of Portugal during the weeks that preceded their departure. The gaps in the narrative were very long--nothing got through between the departure of Masséna from Almeida on September 15, 1810, and Foy’s first arrival at Ciudad Rodrigo on November 8th. There was another lacuna in the knowledge of the situation between that date and the passage of Masséna’s second successful messenger, Casabianca, from Santarem to Rodrigo in the earliest days of February. And after Casabianca had passed by, the next news came out through Foy’s second mission, when he started to announce the oncoming retreat on March 5, and got to the borders of Leon on March 13. The only way in which King Joseph at Madrid, or the generals of the ‘military governments’ of Old Castile, or Soult in Andalusia, felt the course of the war on its most important theatre, was that they were for many months freed from any anxiety about the movements of Wellington. He was ‘contained’ by Masséna, and, however he might be faring, he had no power to interfere by armed force in the affairs of Spain. The French for all this time had to deal only with the armies of the Cortes, and with their old and irrepressible enemies the guerrilleros of the mountains.
