On the 20th of April an attack was made on an entrenchment of the enemy, about six o’clock in the evening. Colonel Sherbroke, commanding the advanced posts, directed the attack. Three different columns were to advance at the same time from Macdonald’s post; one to the left, under Lieut.-Colonel Michael Monypenny, of the SEVENTY-THIRD, consisting of four companies of that regiment, and four of the Bengal volunteers, was to proceed along the bank of the river Cavery, and to turn the right flank of the enemy’s entrenched post. Another, to the right, consisting of the flank companies of the twelfth regiment, and two companies of Bengal volunteers, under Lieut.-Colonel Gardiner, was to move along Macdonald’s nullah, and to turn the enemy’s left. The centre column, composed of six companies of the SEVENTY-THIRD, and four of the Bengal volunteers, under Brevet Lieut.-Colonel the Honorable George St. John, (Major of the SEVENTY-THIRD regiment), was directed to make a feint, which was to be converted into a real attack, should it be deemed expedient. The three columns at dusk, advanced under a well-directed fire from the guns which commanded the entrenchment. The enemy’s resistance was unavailing, and the several attacks were completely successful. It was afterwards ascertained, that the enemy had two hundred and fifty men in killed and wounded, and it is remarkable, that although about eighteen hundred of Tippoo’s infantry occupied the entrenchment, the British, in this attack, had only one man wounded.[7] The siege of Seringapatam was prosecuted with vigour. On the 26th of April, the SEVENTY-THIRD had Lieutenant James Todd wounded; and Lieutenant Archibald John Maclean was wounded on the following day. A breach being reported practicable on the 3rd of May, the assault was ordered, and the SEVENTY-THIRD regiment was selected to take part in this enterprise, which was ordered to be commenced in the heat of the following day, as the enemy’s troops would then be the least prepared to oppose the attack. The assault took place about half-past one o’clock in the afternoon of the 4th of May, and the troops for this service, commanded by Major-General David Baird, were divided into two columns of attack. The SEVENTY-THIRD, with the seventy-fourth regiment, four European flank companies, fourteen Sepoy flank companies, with fifty artillerymen, formed the right column, under Colonel Sherbroke. Each column was preceded by one serjeant and twelve men, volunteers, supported by an advanced party of one subaltern and twenty-five men. A brigade of engineers, under Captain Caldwell, accompanied the storming party; Lieutenant James Farquhar, of the seventy-fourth, commanded the European pioneers, and Lieutenant John Lalor, of the SEVENTY-THIRD, both of whom had examined the ford, conducted the columns.
