His compliance proved useful: Stapleton Cotton arrived in London shortly after and ‘expressed himself decidedly against Sir William Beresford’s claims, and with some warmth.’ Lord Bathurst explained to him that Graham’s consent to the ‘temporary arrangement’ must govern his own, and tried to put him off the idea that he himself would undoubtedly become Wellington’s destined successor, if Graham refused the post, by hinting that after all Graham might recover his eyesight, and be able to take over the command. After showing much soreness, Cotton reluctantly acquiesced. The War Minister, writing an account of the interview to Wellington, ends with ‘I think it necessary to have this explained beforehand, that you might not have any doubt whether you were, after what has passed, to consider Sir Thomas Graham or Sir Stapleton Cotton as the person who was to exercise the command in case of your personal indisposition[339].’ So Beresford’s nomination was passed, as Wellington desired, and contrary to the Duke of York’s views as to the inevitable power of old precedent. But it was only passed by the consent of the other parties concerned, however reluctantly given. Fortunately Wellington preserved his usual splendid health, and the experiment of trusting the whole Allied Army in the Peninsula to the victor of Albuera was never made. On another great controversy which (since Wellington never went off duty for a day) was of more practical importance than that of the right of succession, the Duke of York was partly successful in discomfiting the Commander-in-Chief in Spain. This was a question on which there had been much argument at the end of each Peninsular campaign, but never so much as in 1812-13. The exceptionally heavy casualty lists of the storming of Badajoz, the battle of Salamanca, and the retreat from Burgos had brought a great number of units, both cavalry and infantry, to very low figures. There were (as has been mentioned in a previous chapter) twelve battalions which had at the end of the retreat less than 300 bayonets effective, thirteen which had more sick than men present with the colours. For some of these the difficulty was only a momentary one--there was a large draft on the way to reinforce the unit, or at least a good number of trained recruits in Great Britain ready to be sent out. But this was not the case with all of them: the reason of this was to be sought in the organization of the Army in 1812: the majority of infantry regiments had two battalions; if the second unit was on home service, it regularly found drafts for the one at the front. But if the regiment was a single-battalion corps (and there were seven such with Wellington[340]), or if it chanced to have both units abroad and none at home (as was the case with fifteen other corps[341]), there was only a dépôt in Great Britain, and this had to feed two battalions both on active service overseas, and often could not discharge the double task effectively.
