There was still no news from the expedition to Quebec, and no word from Colonel Knox. When General Schuyler at Albany wrote to bemoan his tribulations, Washington responded, “Let me ask you, sir, when is the time for brave men to exert themselves in the cause of liberty and their country, if this is not?” He understood the troubles Schuyler faced, “but we must bear up against them, and make the best of mankind as they are, since we cannot have them as we wish.”
