"Sir, "The same sentiments of humanity which induced your Excellency to propose to me to capitulate, lead me, now that I am fully acquainted with your force, that I have taken eight officers and upwards of 1000 men and killed more than double that number, without your having reached the centre of my position, the same sentiments, I say, lead me, in order to avoid a further effusion of blood and to give your Excellency a fresh proof of Spanish generosity, to offer to your Excellency, that if you choose to re-embark with the remainder of your army, to evacuate Monte Video and the whole of the river Plata, leaving me hostages for the execution of the treaty, I will not only return all the prisoners which I have now made, but also all those which were taken from General Beresford.
