Prince Poniatowski immediately looked up at Sais,
"Are you referring to..."
"The Prussians." The latter pointed at the map towards Gdansk in the northwest of Poland, "I assure you, as soon as Russia declares war on you, William II will immediately attack here."
"Although I fully understand your prudence, all current signs suggest that Prussia has not betrayed the 'Bo Pu Alliance.'" The Prince politely retorted, "In fact, a few months ago, His Majesty William II sent a personal letter expressing his ardent support for our new constitution."
Joseph had long warned the Poles to be wary of Prussia, but William II's disguise was too convincing, making it difficult for the Poles to harbor any doubts.
As the Polish Intelligence Department also noticed Russia's military movements, when France warned of a Russian invasion, they didn't hesitate to start preparing actively for war.
