On March 13th Wellington reluctantly carried out the orders from the Horse Guards as regards his depleted cavalry regiments: the 4th Dragoon Guards, 9th and 11th Light Dragoons, and 2nd Hussars of the German Legion were ordered to make over their effective horses to other regiments, and to prepare to embark at Lisbon. A paragraph in the General Orders expressed Wellington’s regret at losing any of his brave old troops, and his hope that he might yet see them again at the front[348]. As to the infantry, the Duke repeating his general precept that depleted battalions must come home, but not giving definite orders for them by name and number, a curious compromise took place. Wellington sent back to England the two weakest units, which were still in April well under 300 bayonets apiece[349]: he had already drafted a third into the senior battalion of its own regiment, which was also in the Peninsula. Four more of the war-worn battalions had been worked up to about 400 of all ranks, by the return of convalescents and the arrival of small drafts--Wellington ventured to keep them, and to report them as efficient battalions, if small ones[350]. The challenge to Home authority lay with the remaining six[351]: though five of them were well under 400 strong he nevertheless stuck to his original plan and formed three provisional battalions out of them. If the Duke of York wanted them, he must ask for them by name: he did not, and they kept the field till the end of the war, and were repeatedly mentioned by Wellington as among the most efficient units that he owned. Presumably Vittoria put his arrangements beyond criticism--at any rate, the controversy was dropped at the Duke’s end. The net result was that Wellington lost three depleted infantry units and four depleted cavalry units of the old stock--about 2,000 veteran sabres and bayonets. In return he received before or during the campaign of 1813 four new cavalry regiments--all hussars[352]--and six new infantry battalions[353] all much stronger than the units they replaced, and making up about 1,600 sabres and 3,000 bayonets. He would probably have said that his real strength was not appreciably changed by getting 4,500 new hands instead of 2,000 old ones. Certainly, considering the effort that was required from the Peninsula Army in 1813, it is sufficiently surprising that its strength was, on balance, only four infantry units to the good--the cavalry regiments remaining the same in number as in 1812.
