A man is thrashing in "a swift-flowing river" (I am not sure if it is correct to say "a swift-flowing river" to mean the flow of the river is running very fast).
Is it correct to say "We rescued the man in the river" and "We rescued the man from the river" in this situation?
I feel like, in the first sentence, "in the river" modified the noun "the man", not the verb "rescue".
and in the second sentence, "from the river" modified the verb "rescue", not the noun "the man".
