Questions & Answers about Nous avons dû débarquer vite.
Why is devoir in the passé composé (avons dû) rather than the imparfait (devions)?
Why is there a circumflex accent on dû?
The circumflex is there solely to distinguish the past participle of devoir from the partitive article du (meaning "some" or "of the"). You drop the accent in the feminine or plural forms (due, dus, dues) because there is no risk of confusing them with other words.
Does débarquer strictly mean "to disembark" from a boat?
Could vite be placed earlier in the sentence, such as Nous avons vite dû débarquer?
