FROM HIS ROYAL HIGHNESS THE COMMANDER-IN-CHIEF TO THE MINISTER OF WAR OF HIS BROTHER THE EMPEROR OF PATAGONIA. (Begins) I have the honour to report: Upon the morning of Sunday, the 31st, the enemy attacked the left of my position in great force, a little before dawn. I withdrew the XIth, XIIIth, and IInd Brigades, which were here somewhat advanced, covering their retirement with detachments from the First, the Thirty-seventh, and the Forty-second of the Line. The retirement was executed in good order and with small loss, the total extent of which I cannot yet determine, but of which by far the greater part consists of men but slightly wounded. Several pieces which had been irretrievably damaged were destroyed and abandoned. Upon reaching a position I had determined in my general plan before leaving the capital (see annexed sketch map A) the forces entrenched, defending a line which the enemy did not care to attack. I have reinforced the Brigade with two groups drawn from the Corps Artillery, and have despatched all aids, medicaments, etc., required. A simultaneous attack delivered upon the centre of my position was repulsed, the enemy flying in the utmost disorder, and leaving behind them two pieces of artillery and a colour, which last I have sent under the care of Major the Duke of Tierra del Fuego to be deposited among the glorious trophies that adorn the Military Temple. By noon the action showed no further development. In the early afternoon I determined to advance my right, largely reinforced from the centre, which was now completely secure from attack. The movement was wholly successful, and the result coincided exactly with my prearranged plans. The enemy abandoned all this upper portion of the right bank of the Tusco in the utmost confusion; his main body is therefore now in full retreat, and there is little doubt that over and above the decisive and probably final character of this success I shall be able to report in my next the capture of many prisoners, pieces, and stores. I congratulate His Majesty upon the conspicuous courage displayed in every rank, and recommend for distinguished service the 1847 names appended. His Majesty’s Government may take it that this action virtually ends the war. (Ends.)
