Howe needed to reach Montagu before the French battle fleet could find his detached squadron. Montagu had eight 74-gun ships and one 64, accompanied by two frigates. That was a useful independent force, but it was too small to face Villaret-Joyeuse's fleet, particularly with Nielly's reinforcements. Howe's search therefore also aimed to prevent an isolated British squadron from meeting a much stronger enemy.

Howe's pursuit also protected Montagu's detached squadron
Montagu's nine ships of the line were vulnerable to the French battle fleet, giving Howe another reason to pursue and make contact.
