Meanwhile, over at Plain Fortress, the Giant Eagle Knights had finished confirming the intelligence.
The results had indeed been exactly as expected. Part of the Holy Roland Empire's follow-up reinforcements had already arrived at Copper Furnace Fortress. By now, the mountainside camp there had gathered at least five or six thousand troops.
