5: An intact harbour makes disembarking troops and equipment from your ships a whole lot easier than landing on a beach or coast, magic or not.

And guess what kind of town Harjeon is? Right, it's a Harbour Town, so exactly what Alvarez needs for an efficient landing and efficient resupplying of their troops... at least the sea-going troops.

They have too many troops to land and supply them all by airship, especially after Jupiter decimated their air-fleet.
