By the end of January through redeployment and wastage (through disease and desertion) the number had fallen to 52,000 of whom only 28,000 were available for field operations; the others were either on garrison duties or guarding the lines of communication back into France. Suchet thought that the armies under the command of the Spanish General Copons and the British General Clinton amounted to 70,000 men (in fact they only had about as many as he did), so Suchet remained on the defensive. On 10 January 1814 Suchet received orders from the French War Ministry that he withdraw his field force to the foothills of the Pyrenees and to make a phased withdraw from the outlying garrisons. On ratification of the Treaty of Valençay he was to move his force to the French city of Lyons. On 14 January he received further orders that because the situation was so grave on the eastern front he was to immediately send further forces to the east, even though ratification of the Treaty of Valençay had not been received. This would reduce the size of Suchet's field army to 18,000 men. The Allies heard that Suchet was hemorrhaging men and mistakenly thought that his army was smaller than it was, so on 16 January they attacked. Suchet had not yet started the process of sending more men back to France and was able to stop the Sicilians (and a small contingent of British artillery in support) at the Battle of Molins de Rey because he still had a local preponderance of men. The allies suffered 68 casualties; the French, 30 killed and about 150 wounded. After Suchet sent many men to Lyons, he left an isolated garrison in Barcelona and concentrated his forces on the town of Gerona calling in flying columns and evacuating some minor outposts. However his field army was now down to 15,000 cavalry and infantry (and excluding the garrisons in northern Catalonia). The last actions in this theatre happened at the siege of Barcelona on 23 February; the French sallied out of Barcelona to test the besiegers' lines, as they thought (wrongly) that the Anglo-Sicilian forces had departed. They failed to break through the lines, and forces under the command of the Spanish General Pedro Sarsfield stopped them. The French General Pierre-Joseph Habert tried another sortie on 16 April (several days after Napoleon had abdicated) and the French were again stopped with about 300 of them killed. Habert eventually surrendered on 25 April.
