His father, Murad the Second, had died in February 1451 at Adrianople. When Mahomet learned the news he was in Magnesia. Calling upon all who loved him to follow, he hastened as rapidly as possible to Gallipoli. During the two days he remained there a great crowd flocked to his standard. Then he pushed on to Adrianople. On the day after his arrival he was proclaimed sultan. Halil Pasha the grand vizier and Isaac Pasha were in attendance, but as they were the advisers who prevented the young sultan from retaining supreme power, they were doubtful of their reception and kept themselves in the background. Mahomet, however, ordered Halil to take his place as grand vizier and appointed Isaac Pasha governor of Anatolia or Asia Minor. Mahomet commenced his reign by one of those acts of cruelty which at once proclaimed the brutal and the treacherous side of his character. Being himself the son of a slave mother and having a younger brother, named Ahmed, an infant still at the breast, who was the son of Murad by his marriage with the sister of the Serbian kral, he ordered a certain Ali to drown the young Ahmed in his bath. His predecessors had killed their brothers, but the latter, as we have seen, were in open revolt. Von Hammer states that there are Turkish historians who praise Mahomet the Second for this act of cruelty, and this for the reason that it is easier to kill a babe than a boy who is grown up.[194] Fearing apparently the effect so wanton an act of cruelty would have upon his followers, Mahomet disclaimed all participation in it and put Ali to death.[195] Mahomet is entitled to be classed among the men who at an early age showed exceptional military skill. This skill was developed during almost continual warfare to the end of his reign. His industry, his boundless desire for conquest, his careful attention to every detail that was necessary to secure success, and his confidence in his own judgment, recall the names of Alexander and Napoleon. From his first and most important enterprise against Constantinople itself down to the last expedition of his reign he was not merely the nominal but the actual commander of the Turkish troops. He would brook no interference. He allowed no council or other body of his subjects to thwart his designs. The New Troops or Janissaries, flushed with victory and already conscious of that solidarity which in later years made them the terror of sultans, exacted from him a donative on his accession, but they paid dearly for their temerity and soon learned that their new master would neither be dictated to nor divide his sovereignty.
