The troops were called out without any one knowing against whom the campaign was to be made. They marched towards the Rhine till they reached Tralenburg, which belonged to the Harlungs and where the brothers then lived. Two horsemen kept watch by the river. When they saw the armed men, they feared something was wrong, and, dismounting, swam with their horses across the river. They gave the alarm, and all was prepared for defence. Imbreke and Fritele knew the science of war; but they were still very young, and Eckehart, their governor, was detained at Breisach by business of the state. When the Harlungs saw their uncle’s banner, they thought all danger was over; but soon found to their cost that it was a warlike and not a peaceful visit. Wittich and Heime were with the imperial army; but as soon as they learnt Ermenrich’s plans they rode away to Breisach to warn the faithful Eckehart of what was going on. As they journeyed together, they became good friends again. Tralenburg was at length reduced by fire and taken by storm. Without seeing his nephews, Ermenrich ordered a gallows to be erected, and the two brothers to be at once hung thereon. In those days the word of a mighty potentate was law, and the emperor was obeyed without remonstrance. Ermenrich now took possession of the Harlungs’ land, and sent out men to search for the rich hoard the murdered princes had inherited from their father. It was at length found hidden in a cave. The emperor rewarded his army richly, and kept the rest of the treasure-trove for himself. Meanwhile Heime had returned. He had come back intending to reproach his liege lord with his evil deed, and to throw up his fief. But on receiving a large share of the booty, he forgot his better purpose. He was entrusted with the care of taking the treasure to Romaburg. When he saw the heap of red gold and precious stones, he took care that a considerable portion of it should find its way to Studa’s grange, and not to Romaburg. Meanwhile curses both loud and deep were uttered in every land against the emperor. Eckehart brought the news of the Harlungs’ fate to Bern, and Dietrich’s wrath burned when he heard it. He said the time would surely come when he could demand expiation from Ermenrich, and punish his evil counsellors Sibich and Ribestein. The fiery young heroes Alphar and his brother Sigestab wished to start at once alone with Eckehart to avenge the murder. But their father Amelolt and Hildebrand persuaded them to wait. “What is only put off may yet be done,” said Alphar to his brother, laying his hand upon his sword. Somewhere about this time Sibich and Ribestein met to hold counsel as to what they should do next. “Another stone is out of the way,” said Sibich; “now we must try to find levers strong enough to move the great rock that stands in our way.”
