But there's a huge difference between the North and the Riverlands. The riverlands are a smaller area full of rivers (I know, you're gonna say "Well, duh"), and the Ironmen's ships can sail in even shallow rivers. All they had to do was move the longships from the sea to the rivers, which Vikings in the real world did, and perform blitzkriegs along the rivers moving from place to place quickly, making it difficult to for the Storm King to form a united front when the ironmen were everywhere. As Sun Tzu said the best general was the one who avoided battle.
The North, by comparison, is almost as large as the South and doesn't have as many rivers traversing the landscape. The ironmen would have to go on foot for the most part to travel through the North, and Asha notes that Ironmen lack the discipline to withstand an armored charge such as when Dagmer's shieldwall broke at Torrhen's Square.
Very true, even his favored heir, Asha, knew conquering the North was a fool's errand, knowing that Balon was blind in some respects.
