You didn't underline anything. However, I can see that there are two prepositions in this sentence, and those are the words <em>into </em>and <em>of, </em>which means those are definitely underlined here.
An object of a preposition refers to words which follow a particular preposition. So, having this in mind, the word that follows into is crowd, and the word that follows of is soldiers. The correct answer is crowd; soldiers.
