When the Commander moved to the north, he introduced the knights to an aspect they were less familiar with: battle formations.
After extensively looking into the way that Chemois had lost so many of their men during the monster war, Henry communicated with Commander Lothian about what could have gone better for them. What they noticed the most was, at most, knights and their apprentices as battle partners taking on walls of goblins. If they could have had a wall themselves, they likely would have had more success at the beginning of the war.
The Knights of Hydrogia were a larger order of knights in comparison and were able to overwhelm most goblin waves on sheer numbers alone, but it wouldn't work for a smaller order.
