Strange Helm Deep Recapture

[rezha]

Helm's Deep was captured by saruman. Later in the game ha moved all the army to the east, and left no one on it.

So i moved aragon alone to helms deep, and used a card (i dont remember the name) that states something like "play in edoras or in a rohan region with an hero, recuirt 1 units of rohan", and automatically recapturend helms deep.

Is this a right use of the card?

All recruitment cards need the Region that they recruit in to be free (a free Region is a Region free of enemy armies and/or enemy controlled Settlements), since Aragorn/Strider can't retake Helm's Deep on his own it wasn't a Free Region, you couldn't play it.

You should have left Aragorn/Strider one Region away from Helm's Deep, played the card and then retaken the Stronghold.
