Thanks guys!

I have a question regarding the movement of ships. The explanation could get confusing so I will try to explain it clearly. Using revised rules/objectives here.

1. My ship, a cruiser, is attacked by an enemy fleet of destroyers who begin movement from a naval port (total possible move of 3) during my opponent’s turn.
2. Enemy ships all move two spaces to engage in combat.
3. During combat, my ship is destroyed.
4. After destroying my cruiser, my opponent wants to move the enemy fleet one more space into an adjacent sea zone containing 2 of my ships and initiate another combat phase during their same Combat Phase.

Is my opponent allowed to do this move and attack in the same Combat Phase? If not, are they allowed to use the ships’ remaining move (1) during their Non-Combat Movephase to move their ships into the adjacent seazone where my ships are?

Thanks for the help in advance. If you need more clarification please ask.
