Corsair Ships - Move Ships & Transport

[renskemo]

The rules indicate that Corsair ships can be moved two regions using 1/2 Army die, and that armies can move by ship transport using 1/2 muster die.

If I have Corsair ships in Umbar and Pelargir, and an army in Umbar, can I use a single Army die to both move a ship from Pelargir to Dol Amroth, and then transport the Umbar army to Dol Amroth?

My opponent thought that this might mean illegally "using" a Corsair ship twice with the same die.

You can do that as long as the Region you are moving to (landing in) is free from enemy units (or you are besieging a Stronghold in the Region). An attack takes the entire Action die usage.
