I felt my bosom swell—
For the words rang as a knell,
And the voice seemed his who fell
In the battle down the dell,
And who is happy now.

And this the plighted vow,
And, though my faith be broken,
And, though my heart be broken,
Unlike the other stanzas, this one is perfectly iambic, without extra unstressed syllables slipped in-between. Ironic, considering the fact that this is when the speaker feels the least perfect.

Anaphoras are repetition of certain words among lines.
