Still hoping to arrest the purple tide of civil war, Gregory despatched legate after legate to Henry, charging them to omit no lawful means to incline the monarch to peace, and induce him to abide by the decision of a diet which should be convened to judge between him and his rival. This was the pacific adjustment to which the Pontiff looked. But Henry remained deaf to all these remonstrances, constantly declaring that the sword alone must decide. He was again at the head of a powerful army, and burned to retrieve the lustre of his arms. Rodolph, perceiving that another battle was inevitable, prepared for it without delay. Each king was now in quest of the other.

They met near Fladenheim in Thuringia. As at Melrichstadt, the allied forces of Suabia and Saxony were drawn up in two divisions under Rodolph and Otto. The former occupied a steep hill on the bank of a deep stream, which separated the combatants. Otto with his Saxons was stationed in the van, and was to sustain the attack, while the division of Rodolph was to act as a reserve. It was a bitter cold day in January, and a thick mist had canopied the river. Under cover of this, Henry, by a retrograde movement, gained the rear of his adversary. Rodolph, unconscious of this, was anxiously listening for the din of battle as the fog partially obscured his view. Gilbert had never seen the new king's noble brow so calm and unclouded—he had never seen his eye flash so proudly and joyously, or the same sweet, buoyant smile upon his lips. But as the hostile army filed out into the plain, and Rodolph found that the enemy he had expected in front was in his rear, a deep frown for a moment dispelled his smiles. It was only for a moment. He saw that Henry was now between him and Otto.

"Ride to my noble Otto," he said to Gilbert, who was at his side, "and bid him charge at once." Before Rodolph had altered his array, Gilbert brought back the Saxon's answer:

"Otto of Nordheim declines to abandon the advantages of his position, and says he will not fail you, should you require his assistance."

"It is well," said the king, frowning slightly; "he will not fail us." Then turning to Albert of Hers, he said, in a whisper: "Otto wishes the glory, of deciding the day, as at Melrichstadt. Let us try that he may obtain the laurel of victory instead of the odium of defeat. Gentlemen!" he said, in a loud voice, exchanging cheerful smiles with the Suabian nobles around him, "you have now an opportunity of meeting face to face the desolators of your country. Soldiers!" he said, mingling among his troops, "there are the Bohemians who butchered your wives and families!" As the whole body clamored for the signal to begin, Rodolph gave the word, and the chivalry and yeomanry of Suabia swept rapidly down the hill. They were met at the base by the whole army of Henry. Still, nothing daunted, Rodolph displayed his impetuous valor, the lords of Hers and Stramen rushed on the destroyers of their castles, and Gilbert and Henry fought side by side, each trying to outstrip the other. At this moment, as Rodolph was tugging at his lance to draw it from a body of a knight he had pierced, it was seized by Vratislaus, Duke of Bohemia. As Vratislaus put forth all his strength to disarm his antagonist, Rodolph suddenly yielded up the weapon, and as the duke staggered back, sprang upon him with his sword. Timely succor alone saved the Bohemian.

"He will be rewarded for capturing my lance," said Rodolph, calmly. "Had not his friends been so fleet, he might have had his recompense in another world."

But the Suabians, opposed to three times their number, were beginning to retreat, when Otto of Nordheim, true to his word, emerged from the mist and fell upon the enemy's flank.

"Well done, thou Saxon eagle!" exclaimed Rodolph, eagerly, seeing the discomfited foe staggering before this unexpected and vigorous attack. "Henry of Stramen, ride to the duke, and tell him he has won the day."

Rodolph, surrounded by some of his barons, among whom were the lords of Hers and Stramen and Gilbert, was posted upon a little knoll, watching the progress of the fight, when Henry returned with Otto's acknowledgments to the king.

"Sire!" said Albert of Hers, riding up to the monarch, "your cunning rival there has profited by this mist, and I think we may now turn it to our account."
