Gustavus was justly indignant. He said: "I am very much astonished that when the liberties of Germany and the Protestant religion are at stake the citizens of Frankfort talk of annual fairs, and postpone for temporal interests the great cause of their country and their conscience." He continued: "I have managed to find the keys of every town and fortress from the Island of Rugen to the Main, and I know where to find the key of Frankfort. The safety of Germany and the freedom of the Protestant faith are the sole objects of my invasion. Conscious of the justice of the cause, I am determined not to allow any object to impede my progress. I am well aware that the inhabitants of Frankfort wish to stretch out only a finger to me, but I must have the whole hand to grasp." With his army he escorted the deputies back to the city, and in full battle array awaited the decision of the city. The gates were immediately opened and the entire army marched through the old imperial city, making a magnificent procession conducted in wonderful order. Here again the Protestant princes came to offer congratulations, to secure favors, or to appease his indignation at their heavy apathy. It was in Frankfort that the crown was yet voted upon, and placed on the one selected as head of the Holy Roman Empire. Queen Eleanor Marie here visited him in company with Chancellor Oxenstiern. Neither of them approved of the brilliant court surrounding Gustavus, and the queen, with the swift intuitive knowledge which God gives to good women, felt that underneath all these protestations these Protestant princes had envy and jealousy in their hearts. Oxenstiern, that keen judge of men, came to the same conclusions. The king felt these things himself, and felt, also, that these princes, so divided among themselves, had little religion worth defending. He occasionally broke out in public, showing his surprise and pain at the attitude of their minds. On one occasion he said: "I wish to make peace if I am offered honorable conditions, such as will secure the welfare of the Protestant princes and their oppressed subjects, for whose sake I have undertaken this war and shed my blood. But I shall never conclude a peace by which the honor of Protestant princes would be sacrificed, their unhappy subjects bear an iron yoke, and our religion compromised."
