And while they fought, if they remembered to fight:
So earnest were they to pack into that hour
Their unwilling hoard of song before the moon
Grew brighter than the clouds. Then 'twas no time
For singing merely. So they could keep off silence
And night, they cared not what they sang or screamed;
Whether 'twas hoarse or sweet or fierce or soft;
And to me all was sweet: they could do no wrong.
Something they knew- I also, while they sang
And after. Not till night had half its stars
And never a cloud, was I aware of silence
Stained with all that hour's songs, a silence
Saying that Spring returns, perhaps to-morrow.
The manic thrush song was a song of life, which is now “silence”. So, the fluctuating certainty and uncertainty of the first line is repeated. The poet knows that Spring will return. However, time is in question. It is “perhaps” tomorrow, as he says in the opening sentence.
