I was reading "Birches" by Robert Frost. I am having difficulty in understanding the meaning of a part of a line.
Please refer to this link for the full poem: https://www.poetryfoundation.org/poems/44260/birches
What is the meaning of this part (of a line):
...And not one but hung limp, not one was left For him to conquer.
Does it meaning that all the trees except one hung limp and that he had conquered every tree?
