“We ourselves are not sufficiently safeguarded to repel… an attack and we fear lest the enemy, who is already so near, should besiege us also… Therefore, we humbly appeal to Your Holy Majesty to… come to our aid as quickly as possible and to support us. For we are completely devoted to Your Majesty, even if we perish.
