The only real gain to the English army at the end of the day was the possession of the Plaza de Toros: and its situation was such, that, if fortified, it would have commanded the town, and perhaps compelled the inhabitants to insist on a surrender. Captain Frazer urged this without success: he pointed out that with some guns captured that day from the Spaniards he could construct a battery of 26 guns, immediately serviceable, and strengthen it by unspiking 10 other pieces of ordnance which had been for a time rendered unserviceable by the enemy, prior to their capture: he assured the General that there were not less than 600 barrels of powder, captured that day in the Arsenal of Buenos Ayres, and an apparent abundance of every requisite for the service of a battery; and he reminded him that each gun which they had brought from Monte Video was provided with 200 rounds: but all was to no purpose. A loop-hole for an escape without utter disgrace, as he thought, was opened to General Whitelocke, of which he availed himself, and which he thus described in his official report:--“On the morning of the 6th inst. General Linières addressed a letter to me, offering to give up all his prisoners taken in the late affair, together with the 71st Regiment and others taken with General Beresford, if I desisted from any other attack on the town, and withdrew His Majesty’s forces from the River Plata, intimating at the same time, from the exasperated state of the populace, he could not answer for the safety of the prisoners, if I persisted in offensive measures. Influenced by this consideration (which I knew from better authority to be founded on fact), and reflecting of how little advantage would be the possession of a country, the inhabitants of which were so absolutely hostile, I resolved to forego the advantages which the bravery of the troops had obtained, and acceded to the annexed Treaty, which I trust will meet the approbation of His Majesty.” It may be here mentioned that the Treaty was carried out; the English army returning to Monte Video, and [Sidenote: MS.

But as, fortunately, an immense number of private and unpublished papers on this subject had been accumulated by Sir A. Frazer, and ultimately reached the Royal Artillery Record Office with a view to embodiment in some such work as this, it seems desirable to analyze the conduct of General Whitelocke at this crisis, and to ascertain, as far as is practicable, whether any other course would have been successful.
