Explanation:

Both the poems are written by the same person, Denise Levertov, a British poet. She seems to be too concerned about the ravages of war, the destruction and distress it results in.  

Both the poems are about the tragedy of war that struck Vietnam. She seems to be much perturbed at the scene witnessed in Vietnam.  While the second poem talks about white phosphorus seeking the bones, the first talks about the burning Vietnamese flesh.

Thus, both the poems portray the horrors of war.
