After a short expedition he returned to Kâbul, having set a faint finger-mark on the extreme north of India. In the next five years he is said to have made three more expeditions into the Punjâb, but the Memoirs are again silent as to these, and they appear to have been insignificant. But the idea of Indian conquest was not dead, and in A.D. 1524 it burst forth again into sudden life. The cosmic touch which roused it being the appeal of the rightful heir to the Kingdom of Delhi for help against his nephew Ibrahîm Lodi, who, he said, had usurped the throne. At the same time Babar's governor in the Punjâb begged the emperor to come to his aid.
It was the psychic moment, and Babar was prepared for it. He marched instantly on Lahôre, and finding affairs unsatisfactory, paused ere going further to return to Kâbul, and beat up reinforcements with which to secure his line of retreat. Coming back, he found it necessary to settle the governor, an old Afghân, who had broken into rebellion, and who, girding on two swords, swore to win or die. He did neither, for Babar, catching him red-handed in rebellion with the two swords still hanging round his neck, forgave him--as he was inclined to forgive all men.
So, free at last, he set his face towards Delhi. What the state of India was at this time we know. It was one of countless jealousies, seething rebellions, open disunion--on all sides conquest seemed possible; but Delhi had been the goal of Timur, so it must be the goal of his descendant.
Curiously enough, this last, and in all ways most decisive attack from the North-West on India did not come as those of Mahomed of Ghuzni, of Mahomed Shahâb-ud-din Ghori, and of Timur had come, with the returning flight of migratory birds from the summer coolth of the high Siberian steppes. The birds were winging westward in this April A.D. 1526, when Babar, choosing with the eye of a general the old battle-field on the plain near Panipût, set to work entrenching himself in a favourable position. This was a new method of battle to the Indians. So was the laager which he made out of his seven hundred gun-carriages linked together by raw cow-hide to break a possible cavalry charge, and strengthened by shield shelters for the matchlock men. For a whole week, though the army of Delhi--consisting of a hundred thousand troops and a thousand elephants--lay before him, Babar, whose total force numbered twelve thousand, was neither let nor hindered in his work. But then Sultân-Ibrahîm, who commanded the enemy himself, is briefly dismissed by the man whose whole life had been one long fight, as being "inexperienced, careless in his movements, one who marched without order, halted or retired without method, and engaged without foresight."
It was on the 21st that Babar accepted the challenge which followed on a repulsed night-attack which he attempted in order to draw the enemy.
It is interesting to note the formation Babar adopted. The laagered guns in front; behind them--the line broken at bowshot distances by gaps through which a hundred horsemen could charge abreast--the right and left centre, right and left wing. Behind that again the reserve, and the cavalry left over from the flanking parties at the extreme right and left.
On came the Indians at quick march, aiming at Babar's right; finding the enemy entrenched, they hesitated, and pressure from behind threw them into disorder. In an instant the Mongol cavalry charged through the gaps, took them in rear, discharged their arrows, and galloped back to safety. This is their national manœuvre, and proved once more of deadly effect, as it had done in the days of Timur.
But the battle waged fiercely, uncertainly. At one time Babar's left, over-rash, might have been overwhelmed, but for his watchful eyes, his instant support.
So as the sun rose high, the wavering victory chose the side of the Northerners. The Southerners, driven into their centre, were unable to use what strength they possessed, and by noon Sultân-Ibrahîm himself lay dead, with fifteen thousand of his finest troops. The rest were in full flight. It had been "made easy to me, and that mighty army in the space of half a day was laid in the dust."
So wrote the victor modestly, though there can be no question that the battle was won by superior generalship.
