Read it through once

The only certain conclusion to be drawn from this letter, which Mr. Echard, in a manner perhaps not so seemly for a Churchman, terms submissive, is, that Monmouth still wished anxiously for life, and was willing to save it, even at the cruel price of begging and receiving it as a boon from his enemy. Ralph conjectures with great probability that this unhappy man's feelings were all governed by his excessive affection for his mistress and that a vain hope of enjoying, with Lady Harriet Wentworth, that retirement which he had so unwillingly abandoned, induced him to adopt a conduct, which he might otherwise have considered as indecent. At any rate it must be admitted that to cling to life is a strong instinct in human nature, and Monmouth might reasonably enough satisfy himself, that when his death could not by any possibility benefit either the public or his friends, to follow such instinct, even in a manner that might tarnish the splendour of heroism, was no impeachment of the moral virtue of a man.
