Again tried to make his peace with the court in January 1792, but he was so insulted that he was not encouraged to sacrifice himself for the sake of the king and queen, who persisted in remembering all old enmities in their time of trouble.
He was not employed again in the field, and personal and political enmities caused him to be neglected and repeatedly passed over.
His interests were secular and he was certainly proud and ambitious; but Stubbs has pictured the fairer side of his character when he observes that Beaufort "was merciful in his political enmities, enlightened in his foreign policy; that he was devotedly faithful, and ready to sacrifice his wealth and labour for the king; that from the moment of his death everything began to go wrong, and 'went worse and worse until all was lost."
Owing to the apathy of the people and the enmities existing among the leaders, the Spanish forces, sent by the viceroy of Peru to crush the revolutionary movement, succeeded after two years' indecisive fighting in completely defeating the patriots at Rancagua in 1814.
His lectures, now framed in a devotional spirit, were heard again by crowds of students, and all his old influence seemed to have returned; but old enmities were revived also, against which he was no longer able as before to make head.
