In addition, the small number of foreign auxiliary troops still left in Spain were ordered back to France, save the remnant of Palombini’s and Severoli’s Italians and the Rheinbund units[369] in the Army of the Centre, viz. the 7th Polish Lancers (the last regiment of troops of this nationality left south of the Pyrenees), the Westphalian horse in the Army of the Centre, and the Berg and Westphalian infantry in Catalonia. Moreover, the brigade of the Young Guard in the Army of the North (that of Dumoustier) and the three naval battalions from Cadiz, which had served so long in the Army of the South, were to come home, also four batteries of French horse-artillery and two of Westphalian field artillery. Lastly, cadres being as necessary for the military train as for any other branch of the service, all the armies were to send home every dismounted man of this corps. The same rule was applied to the _Équipages militaires_ and the Artillery Park. This whole deduction from the Army of Spain under these heads came to nearly 12,000 soldiers of all arms, over and above these cadres. There was an elaborate clause as to reorganizing the Army of the North: in return for giving up four provisional regiments of drafts to the Armies of Portugal and the South, it was to get three regiments made over to it from the former, and one from the latter. Napoleon calculated that it would lose nothing in numbers from the exchange, but as a matter of fact it did. The drafts to be returned to their proper corps ran to over 8,000 men. But General Reille, being told to contribute three regiments to the Army of the North, selected the three depleted units which had composed Thomières’ unlucky division at the battle of Salamanca (the 1st, 62nd, and 101st), which together did not make up 3,000 bayonets[370], though Gazan chose to make over the 64th, a three-battalion regiment with 1,600 men. The Army of the North, therefore, lost nearly 3,000 men on the balance of the exchange, though the Emperor was aware that it was already too weak for the task set it. But he probably considered that Palombini’s Italians, detached (as we have already seen[371]) from the Army of the Centre, would make up the difference.
