The enemy approaching in force, after the raising of the second siege of Badajoz, the Allies crossed the river on the 17th June, 1811, and on the 19th encamped between Elvas and Campo Maior. Elvas had been put in a state of siege, and a position had been marked out behind Campo Maior, in case the French should show any inclination to attack. The bold front which Lord Wellington here showed deceived the two French Marshals, Marmont and Soult, who had now united their armies, and entered Badajoz in triumph, [Sidenote: Major Dickson to D.-A.-Gen. dated 26 June, 1811.] congratulating its gallant governor, Philippon. They concluded that he must have received great reinforcements; and although they crossed the Guadiana with a great body of cavalry supported with infantry, and one or two small affairs with the outposts took place,--they declined a general engagement. A want of _entente cordiale_ between Marmont and Soult led soon to a separation,--the latter moving towards Seville, whither Wellington despatched Blake’s Spanish troops,--and the former marching away by the valley of the [Sidenote: Cust.] Tagus towards Almaraz. Thus relieved of their presence, Lord Wellington took up his quarters at Pontalegre, and allowed his army to have some repose after its recent exertions. This seems a favourable moment for placing before the reader a tabular return (_see next page_) which shows the gradual increase in the Artillery element of Lord Wellington’s army in the Peninsula. Prepared from the monthly returns, it shows the numbers at different periods, distinguishing between the Royal and Foreign Artilleries. The point which will doubtless strike the reader most is the steady increase in the force of Horse Artillery and Artillery drivers, which took place; marking the growing recognition of that which had hitherto been overlooked to a great extent,--the value of mobility in Field Artillery. RETURN of the ROYAL BRITISH and GERMAN ARTILLERY attached to the ARMY under the Command of the DUKE of WELLINGTON in the PENINSULA and FRANCE at the undermentioned periods.
