After the death of Gustavus the Great, Chancellor Oxenstiern became commander-in-chief; he was also chosen chief of the League of the Protestant Princes against Austria. Oxenstiern was as earnest as Gustavus, but the great genius and experience of the Christian soldier, the large wisdom and sincere honesty of the great king were all missing, and made the remainder of the war only a bloody record, with little of the heroic, except the heroism of a steadfast standing to an unpleasant delegated duty. Wallenstein soon recruited a new army, but he now began to be distrusted by both sides.[5] He failed to carry out the Edict of Restitution. He appointed Protestants to good positions in the army. Footnote 5: Read Schiller's "Drama of Wallenstein." Proofs yet exist that he was negotiating with Oxenstiern. Count Schlick openly said: "Wallenstein is playing a double game." He received a messenger from Richelieu. He was aiming first for the crown of Bohemia, and it is believed that his astrologers had told him that the stars proclaimed he would yet be Emperor of Germany. Ferdinand had long watched him through spies, but Wallenstein, surrounded by his great generals, was not easy to take in case he should not choose to submit to arrest. Wallenstein had entered into a bond of friendship with about thirty of his officers, who promised to be faithful unto death to him, but even while the astrologer was telling him of coming triumph, an Imperial proclamation declared that Wallenstein had been found guilty of treasonable conspiracy, dismissed from the service and his officers forbidden to take any orders whatever from him. Wallenstein went to the strong fortress of Eyer in Bohemia, followed by a good-sized army. Here he hoped to maintain himself till he could close negotiations with the Duke of Weimar, with the Swedes and with Richelieu, and carry his army to the other side. But the Emperor was prepared before he made the proclamation. Only four of the thirty officers remained true to him; in spite of their written oaths of allegiance that they would sacrifice their estates and shed their heart's blood for him. The Emperor offered a reward for him dead or alive. These false friends proposed a great banquet in his honor. The banquet lasted late into the night, while they drank to the general's health and toasted him in fair speech. Suddenly a company of ruffians burst into the hall, and, with the assistance of the traitors, the four friends of Wallenstein were assassinated. The general had retired to rest, not being well. Hearing the confusion he rose, dressed and prepared for the worst. Suddenly the tramp of many feet were heard, the door was burst open, and Devereau, at the head of thirty men, cried: "Are you the villain who would betray our Emperor?" Wallenstein, like a brave man, opened his arms wide, receiving in the breast his mortal wound.
