Unfortunately, Augusta, having once entered upon a course of duplicity, was obliged to keep it up by equivocations of all kinds. She went so far as even to show portions of letters addressed to her care, and pretended that they had been written to herself. She seems to have felt no compunction for the sufferings of Lady Byron. She may even have exulted in the pain she inflicted upon that credulous lady, having herself suffered intensely through the false suspicions, and the studied insults heaped upon her by many of Lady Byron’s adherents.

Byron, who was informed of what had been said against his sister by Lady Byron and others, told the world in ‘Marino Faliero’ that he ‘had only one fount of quiet left, and that they poisoned.’ But he was powerless to interfere.

Writing to Moore (September 19, 1818) he said:

‘I could have forgiven the dagger or the bowl—anything but the deliberate desolation piled upon me, when I stood alone upon my hearth, with my household gods shivered around me. Do you suppose I have forgotten it? It has, comparatively, swallowed up in me every other feeling, and I am only a spectator upon earth till a tenfold opportunity offers.’

It may be that Augusta avenged her brother tenfold without his knowledge. But she suffered in the process. Lord Lovelace lays great stress upon what he calls ‘the correspondence of 1819,’ in order to show us that Augusta had confessed to the crime of incest. That correspondence is very interesting, not as showing the guilt of Augusta Leigh, but as an example of feminine duplicity in which she was an adept. Augusta was hard pressed indeed for some weapon of offence when she pretended, on June 25, 1819, that she had received the following letter from her brother. She must have been some time in making up her mind to send it, as the letter in question had been in her hands three weeks, having arrived in London on June 4. It may be as well to state that all letters written by Byron to Mary Chaworth passed through Mrs. Leigh’s hands, and were delivered with circumspection.

‘Venice,
May 17, 1819.[70]

‘My dearest Love,

‘I have been negligent in not writing, but what can I say? Three years’ absence—and the total change of scene and habit make such a difference that we have never nothing in common but our affections and our relationship. But I have never ceased nor can cease to feel for a moment that perfect and boundless attachment which bound and binds me to you—which renders me utterly incapable of real love for any other human being—for what could they be to me after you? My own ...[71] we may have been very wrong—but I repent of nothing except that cursed marriage—and your refusing to continue to love me as you had loved me. I can neither forget nor quite forgive you for that precious piece of reformation, but I can never be other than I have been—and whenever I love anything it is because it reminds me in some way or other of yourself. For instance, I not long ago attached myself to a Venetian for no earthly reason (although a pretty woman) but because she was called ...[72] and she often remarked (without knowing the reason) how fond I was of the name.[73] It is heart-breaking to think of our long separation—and I am sure more than punishment enough for all our sins. Dante is more humane in his “Hell,” for he places his unfortunate lovers (Francesca of Rimini and Paolo—whose case fell a good deal short of ours, though sufficiently naughty) in company; and though they suffer, it is at least together. If ever I return to England it will be to see you; and recollect that in all time, and place, and feelings, I have never ceased to be the same to you in heart. Circumstances may have ruffled my manner and hardened my spirit; you may have seen me harsh and exasperated with all things around me; grieved and tortured with your new resolution, and the soon after persecution of that infamous fiend[74] who drove me from my country, and conspired against my life—by endeavouring to deprive me of all that could render it precious[75]—but remember that even then you were the sole object that cost me a tear; and what tears! Do you remember our parting? I have not spirits now to write to you upon other subjects. I am well in health, and have no cause of grief but the reflection that we are not together. When you write to me speak to me of yourself, and say that you love me; never mind common-place people and topics which can be in no degree interesting to me who see nothing in England but the country which holds you, or around it but the sea which divides us. They say absence destroys weak passions, and confirms strong ones. Alas! mine for you is the union of all passions and of all affections—has strengthened itself, but will destroy me; I do not speak of physical destruction, for I have endured, and can endure, much; but the annihilation of all thoughts, feelings, or hopes, which have not more or less a reference, to you and to our recollections.

‘Ever, dearest,’

The terms of this letter, which Lord Lovelace produces as conclusive evidence against Augusta Leigh, deserve attention. At first sight they seem to confirm Lady Byron’s belief that a criminal intercourse had existed between her husband and his sister. But close examination shows that the letter was not written to Mrs. Leigh at all, but to Mary Chaworth.
