How does the "to" work grammatically?

[seanb]

Hello. I'm now reading the prefatory verse of Alice's Adventures in Wonderland and have a question about its grammar

Here is the text.

4th stanza 1st line.

>Anon, to sudden silence won,

I think it means "soon, suddenly silence occupied." and I'd like to know what the role of "to" is in the phrase.

In my openion it is "to" for consequence. For example : He survived, to the amazement of surgeons. However it cannot be allowed to use past tense form (won) in a noun phrase. So I think the "won" is a past participle which modifies "silence" like : to sudden silence (which was) won

Let me know. Thank you very much!

Thanks for your response
It seems difficult even for native English speaker!
Carroll must have made it enigmatic on purpose, hehe
