On July 25 he plunged fearlessly into Oudh, leaving a wide and rapid river in his rear, with other rivers, canals, and fortified towns and villages in front, on three sides swarms of determined enemies gathered under the standards of Nana Sahib and the Oudh Taluqdars, and everywhere a hostile if not actually mutinous peasantry. With his usual daring, trusting to the unsurpassed élan of his troops, he fought battles at Onao and Busseerutgunge. Then when the thunder of the fighting was faintly heard by listeners in the Residency, Havelock took thought and regretted that he had ventured to leave Cawnpore. His force numbered about half the men who marched out of Allahabad on the 7th. Cholera had broken out; stores were scanty; there was not a single litter for another wounded man; and, worst of all, ammunition was failing. To advance farther meant the total destruction of his little army, the sure and instant fall of the Residency, and the disappearance of the British flag from an enormous territory. Yet he hesitated before he gave the final order. He fell back a couple of marches and wrote to Neill on the 31st that he could "do nothing for the relief of Lucknow," until he received a re-enforcement of a thousand men and a new battery. Neill, who was holding Cawnpore with three hundred rifles, returned the most amazing reply that ever a subordinate officer addressed to his chief. "The natives don't believe you have won any real victories," he wrote, in effect. "Your retreat has destroyed the prestige of England. While you are waiting for re-enforcements that cannot arrive Lucknow will be lost. You must advance again and not halt until you have rescued the garrison. Then return here sharp, as there is much to be done between this and Agra and Delhi." Neill's zeal outran his discretion. Havelock told him in plain language his opinion of this curious epistle. "Your letter is the most extraordinary I have ever perused," he said.... "Consideration of the obstruction which would arise in the public service alone prevents me from placing you under immediate arrest. You now stand warned. Attempt no further dictation." Yet Neill's advice rankled and there were men on Havelock's staff who agreed with the outspoken Irishman. Neill, however, coolly bottled his wrath and sent on a company of the 84th and three guns. They brought despatches from Sir Patrick Grant, Commander-in-Chief at Calcutta, telling Havelock that the troops sent from the capital had been turned aside to deal with mutineers in Behar. The gallant Crimean veteran therefore hardened his heart, set out once more for Lucknow and fought another most successful battle at Busseerutgunge. There could be no questioning either the victory or its cost. Another such success and his column would not number a half battalion.
