The title of the poem pretty much sums up what happens in the poem: the speaker describes a "meeting at night," or rather he describes all the things he must do to make his "meeting" happen. It is only in the last two or three lines that the actual meeting takes place, prompting the question as to what the title of the poem is actually doing.
On the one hand, the title is a little misleading. Why? Because the bulk of the poem consists of descriptions of the landscapes (sea, beach, fields) that the speaker must cross in order to make his date. On the other hand, the fact that the poem is called "Meeting at Night" suggests that the meeting is the most important event in the poem, even though the meeting itself only occupies four lines.
