If Badajoz had held out for a fortnight after March 9th,--and Wellington supposed that it was well able to defend itself for a whole month--the relieving column would have been in good time. The dispatch of March 12th set in motion two divisions from near Abrantes, that of the 15th sent on the third from the banks of the Ceira. Steady marches of twenty miles a day, or a little less, would have brought Stewart and Hamilton to the neighbourhood of Badajoz on the 17th, and Cole with the 4th Division and the dragoon brigade on the 24th[310]. If, as is probable, Beresford had waited for the arrival of the last-named force before presenting himself in front of the French lines, the 24th of March would have been the critical day. It is hard to believe that Soult could have fought to advantage, since he must have left so many men to blockade Badajoz that he could not have faced Beresford with more than 12,000 sabres and bayonets, numbers inadequate to hold off the 18,000 Anglo-Portuguese who formed the allied Army of Estremadura. It is quite probable that he might have raised the siege, and offered battle with his whole army, somewhere south of Badajoz. But into these possibilities it is profitless to inquire. [310] Cole actually reached Portalegre on the 22nd, so could have been in front of Badajoz on the 24th. Since, however, Wellington and Beresford knew on the night of the 14th that Imaz had surrendered, there was no longer the same need for haste that existed down to this moment, and the advance of the Anglo-Portuguese army was made at a moderate pace. Hamilton’s Portuguese were at Portalegre by the 17th, the 2nd Division came in on the 19th and 20th. Beresford himself appeared on the latter day, having ridden through from the neighbourhood of Coimbra in four days. The 4th Division, which had made an admirable march, a hundred and ten miles of mountain road in six days, came up on the 22nd. On this day, therefore, the whole 18,000 men of the expeditionary force were collected within forty miles of Badajoz, and Beresford had to make up his mind as to the course of his campaign. The orders given to him by Wellington had been to concentrate at Portalegre and attack the French, who (as it had now been ascertained) were moving out to besiege the little Portuguese fortress of Campo Mayor, just across the frontier. The small Spanish force under Castaños at Estremos--the wrecks of the old Army of Estremadura--was to be called up to assist[311]. Wellington, who did not know of Soult’s departure for Seville, thought that he could not possibly collect enough men, after garrisoning Badajoz and Olivenza, to enable him to face Beresford. In a supplementary dispatch he told his colleague that he thought it most likely that the Marshal would go south of the Guadiana without accepting battle. In that case the allied army must be careful, when following him, not to trust its communications and line of advance or retreat to any temporary
