Sir Colin, disciplined soldier as he was, bowed to the superior authority and promptly set about the preparations for the Rohilcund campaign. Napier's engineers established a secure military position for the troops appointed to garrison Lucknow. To Hope Grant was given the command of the Lucknow field-force, inclusive of the troops available for the garrison of Lucknow and for operations in the districts; a formidable force the infantry alone of which comprised eleven regiments, with a siege-train, nine batteries, and adequate cavalry. Lugard led a column of all arms into the disturbed Azimghur district beyond south-eastern Oude, which with local reinforcements was to constitute the Azimghur division. On April 8th Walpole's column, in which marched one Punjaub and three Highland regiments with a strong artillery force and two cavalry regiments, started on its road for Rohilcund by way of Sandeela, Rhooyah, and the Ramgunga river. Sir Colin's plan for the invasion of Rohilcund was based on the projected advance of two columns from opposite points; Walpole's force marching up from Lucknow, and a fine body of troops collected at Roorkee by the exertions of Sir John Lawrence, consisting of four infantry regiments, the Mooltan Horse, a field-battery and two 18-pounders under the command of Brigadier-General John Jones. Those columns, sweeping the country during their respective onward movements, were destined to converge on Bareilly the capital of the province, which thus became the objective point of this strategical combination.
