The wind of the downs

The writer uses imagery and lots if repetitions to tell us the poem.
The big idea of the poem is that the girl can't see his face but only his khaki uniform.
She doesn't think he is dead and she can't remember him, that's what the first stanza is about. "brown and tall, "strong and living" these are all metaphors describeing him.
The idea of the second stanza is about that she doesn't want to belive that he is dead amd she is waiting for him to come back while she is doing things they used to do together.
