Clive now determined to push on to the main road, which he knew crossed the fields half a mile in front of him. The country was, however, here laid out in rice fields, each inclosed by banks and ditches. Over these banks it was impossible to drag the guns, and the sailors could only get them along by descending into the ditches, and using these as roads. The labour was prodigious, and the men, fatigued and harassed by this battle in darkness, and by the fire from the unseen guns which the enemy continued to pour in their direction from either flank, began to lose heart. Happily, however, the fog began to lift. The flanks of the columns were covered by bodies of troops, thrown out on either side, and after more than an hour's hard work, and abandoning two of the guns which had broken down, Clive reached the main road, again formed his men in column, and advanced towards the city. The odds were overwhelmingly against him. There were guns, infantry, and cavalry, both in front and behind them. The column pressed on, in spite of the heavy fire, crossed the ditch, and attacked a strong body of the enemy drawn up on the opposite side. While it did so, a great force of the nabob's cavalry swept down on the rear, and for a moment captured the guns. Ensign Yorke, of the 39th Foot, faced the rear company about, and made a gallant charge upon the horsemen, drove them back, and recaptured the guns. Clive's whole army was now across the ditch, and it was open to him either to carry out his original plan of attacking Omichund's garden, or of marching forward into the fort of Calcutta. Seeing that his men were fatigued, and worn out with six hours of labour and marching under the most difficult circumstances, he took the latter alternative, entered Calcutta, and then, following the stream, marched back to the camp he had left in the morning. His loss amounted to thirty-nine Europeans killed, and eighteen Sepoys; eighty-two Europeans wounded, and thirty-five Sepoys; the casualties being caused almost entirely by the enemy's cannon. The expedition, from a military point of view, had been an entire failure. He had carried neither the battery nor Omichund's garden. Had it not been for the fog he might have succeeded in both these objects; but, upon the other hand, the enemy were as much disconcerted by the fog as he was, and were unable to use their forces with any effect. Military critics have decided that the whole operation was a mistake; but although a mistake and a failure, its consequences were no less decisive. The nabob, struck with astonishment at the daring and dash of the English, in venturing with so small a force to attack him, and to march through the very heart of his camp, was seized with terror. He had lost thirteen hundred men in the fight, among whom were twenty-four rajahs and lesser chiefs, and the next morning he sent in a proposal for peace.
