"Break through the fortress? The cost would be too severe."
The fortress sat high, easily defensible and difficult to attack. The troops on the upper route attacked five times in half a day and couldn't shake it at all.
Go around? In fact, they didn't need to circle around. They could just come straight through.
With fortresses on the left and right, Black Iron Avenue in the middle, it didn't block their main army at all.
The problem was, it was easy for the army to move through, but what about the supply line? Even if they didn't consider the supply line, they had to think about the possibility of being attacked from both sides.
The lord of the Muddy Marshes and the island Nobles eventually decided to use a straightforward strategy.
Divide their forces!
The main force would continue to Fertile City, while the divided forces would besiege the fortress to prevent the defending army from emerging.
