And this new grief we bore with us to sea: our precious lives we had, but not our friends. no ship made sail next day until some shipmate had raised a cry, three times, for each poor ghost unfleshed by the cicones on that field.

what theme is best revealed by this conflict?

I would say that the theme revealed by this conflict in the excerpt is grief / sorrow.

Explanation:

In this excerpt, the speaker talks from a very sensitive position, talks about how beautiful their lives was, like if he or she felt nostalgic about the life they had, and how difficult it is to let go. It feels that the speaker is talking about the grief process, the sorrow he / she feels "for each poor ghost unfleshed by the Cicones on that field".
