analysis of a poem (lord byron: i watched thee)?

Question

I watched thee when the foe was at our side
Ready to strike at him, or thee and me
Were safety hopeless rather than divide
Aught with one loved, save love and liberty.

I watched thee in the breakers when the rock
Received our prow and all was storm and fear
And bade thee cling to me through every shock
This arm would be thy bark or breast thy bier.

I watched thee when the fever glazed thine eyes
Yielding my couch, and stretched me on the ground
When overworn with watching, ne'er to rise
From thence, if thou an early grave hadst found.

The Earthquake came and rocked the quivering wall
And men and Nature reeled as if with wine
Whom did I seek around the tottering Hall
For thee, whose safety first provide for thine.

And when convulsive throes denied my breath
The faintest utterance to my fading thought
To thee, to thee, even in the grasp of death
My spirit turned. Ah! oftener than it ought.

Thus much and more, and yet thou lov'st me not,
And never wilt, Love dwells not in our will
Nor can I blame thee, though it be my lot
To strongly, wrongly, vainly, love thee still.

Answer 1

The correct title is: Love and Death
by George Gordon, Lord Byron

Despite Byron's reputation as a womanizer and a world-class object of heterosexual love, he was, apparently, throughout his life romantically attached to men. His handsome servant, William Fletcher, “was at Byron’s side from 1804, when Byron was sixteen, almost without interval until his master died.”

Love and Death:
It was Byron's last poem and is one of his Homoerotic Poems together with The Cornelian, "To Eddleston," If Sometimes in the Haunts of Men, Last Words On Greeceetc.
“On This Day I Complete My Thirty-sixth Year” (1824), as well as "Love and Death" (1824) and “Last Words on Greece” (1824), all three were written for Lukas - a young man he [had] met in Greece, where he died in 1824 after joining the Greek revolt against the Turks.
Byron fled England not only because of a scandal over his affair with his half-sister, but also because of the repressive anti-same-sex laws in England, where the penalty for sodomy was death. Homosexual desire was one of the reasons he first went to Greece and the anti-same sex sentiment in England may account for the famous Byronic stance of lone defiance.

Analysis:
In order to analyze properly, try to paraphrase the poem first and then view it in light of the details I have provided.
Start with the first stanza thus:

I watched you when the opponent was nearby ready to strike him - or you and me. Safety was hopeless - except by being separated from the one loved if to gain liberty.

Lord Byron and His Literature:

Lord Byron was a man whose passion for life seemed unequaled by any of the other Romantic figures. Byron’s personal character, though not entirely so, could be seen in his literature as well as his life.
Lord Byron’s most notable contribution to literature, the Byronic Hero, possessed many qualities which Lord Byron himself displayed in day to day life. The most prominent characteristic that links Lord Byron to his literary characters is his passionate manner by which he pursues life. Whether in the pursuit of women or adventure, the life of Lord Byron and his Byronic Hero holds many similarities.
The way that Lord Byron sought pleasure for himself by his own means was another way which he resembled his literary characters. This attitude of self-reliance is a distinguishing characteristic of both Lord Byron and his literary figures
Lord Byron’s moodiness was a trait that links him with his fictional characters as well. Much of this moodiness was brought on by Byron himself, who ceaselessly got himself into troubling situations through his reckless tendencies. The most notable is his affair with his own half-sister. This brought much grief to Byron as it caused many of his friends and supporters to abandon him. This led to the feeling of alienation which Byron shared with his Byronic Hero. These are just a few of the other characteristics that Lord Byron and his fictional characters have in common.
Though not all of Lord Byron’s characteristics are manifested in his characters, there are many similarities between the two. The many resemblance’s that Byron and his characters share only serve to prove what an interesting figure that Lord Byron was and it makes his literature all the more compelling.

All I have found is way down near the bottom of this page:

It would help to read a bit about Byron's almost endless, complicated love-affairs, as this was the last one.
