He strove with all his might to escape

According to my Wren and Martin textbook, with all his might is an adverb phrase in the given sentence. But what is to escape? Is it an adverb phrase as well?

He strove with all his might to escape.

There are no adverbs in your example, so there are no adverb phrases.

"With" is a preposition and "with all his might" is a preposition phrase functioning as a manner adjunct.

"To escape" is an infinitival clause functioning as complement of "strove".

    This answer, while correct according to its own lights, will doubtless confuse many. The traditional definition 'adverb phrase = phrase acting the same way a single adverb does' is eschewed by CGEL and many other grammarians (and admittedly, since it is also by definition a prepositional phrase {here acting 'adverbially'}, they have a point).

In your example, "with all his might" is the adverb phrase (see BillJ's answer instead), while "to escape" is an infinitive verb phrase.

Edit: I should add that the verb 'strive' takes an infinitive, which in this case is 'escape', which may be easier to visualize through bracketing the adverb phrase: "He strove [with all his might] to escape."
