Analysis of Sonnet 36: Stella, Whence Doth This

Stella, whence doth this new assault arise,
A conquer'd, yielden, ransack'd heart to win?
Whereto long since through my long batter'd eyes,
Whole armies of thy beauties entered in.

And there long since, Love thy lieutenant lies,
My forces raz'd, thy banners rais'd within:
Of conquest, do not these effects suffice,
But wilt now war upon thine own begin?

With so sweet voice, and by sweet Nature so
In sweetest strength, so sweetly skill'd withal,
In all sweet stratagems sweet Art can show,

That not my soul, which at thy foot did fall
Long since, forc'd by thy beams, but stone nor tree
By Sense's privilege, can 'scape from thee.
