Meanwhile, Sir Redvers Buller had evolved a new plan of operations, and decided to attack with his combined force the three hills—Pieter's, Railway, and Hart's. For this purpose the greater part of the artillery was brought from the left bank and concentrated on the right bank, opposite the points to be assaulted. It was in position by the 26th, and began a slow bombardment of the Boer trenches. During the night, the pontoon bridge under Hlangwane was dismantled, and carried down to a point below the Boer bridge, where it was relaid, an operation which was not concluded until 10 a.m. on the 27th.

On the day before, the Dublin Fusiliers had been ordered to join temporarily General Barton's Brigade. It left its position among the rocks of Hart's Hollow about 7 a.m. on February 27th, and, moving down the hill through the deserted Boer laager, halted by the pontoon bridge. Here it was joined soon after 9 a.m. by the Irish and Scots Fusiliers, and came under the command of General Barton.

Pontoon Bridge, River Tugela. February 28th, 1900.

The battalion followed the Scots Fusiliers, and moved along the left bank of the Tugela at the foot of a steep ridge, being covered by infantry and maxim fire from the right bank.

After a march of two miles, and at the point where the Klip River joins the Tugela, the 6th Brigade turned to its left and prepared to attack the Boer position, which, lying some two miles from the river, stretched from the ridges north of Eagle's Nest to the various kopjes constituting Pieter's Hill. General Barton directed the Royal Irish Fusiliers to assault the western end of Pieter's Hill and the Scots Fusiliers the eastern, while the 2nd Royal Dublin Fusiliers formed the reserve.

The assault was successful, and the greater part of Pieter's Hill fell into our hands, but the Boers still held a kopje to the north of the hill, and maintained a heavy fire. General Barton, anxious to complete his victory, directed three companies of the battalion and one company of the Scots Fusiliers to advance against the kopje. 'B,' 'C,' and 'H' were the three companies selected, the first named being on the right and the latter on the left, connecting with the Scots Fusiliers. Guided by Captain MacBean, Royal Dublin Fusiliers, Brigade-Major 6th Brigade, the detachment advanced about 2.30 p.m., and came at once under a heavy rifle and pompom fire. The companies pushed forward, however, by successive rushes until they reached a donga some three hundred yards from the kopje. Here further progress was checked for a time, and General Barton ordered forward three companies of the Royal Irish Fusiliers. The latter came up about 5.30 p.m., and, supported by the covering fire of 'B,' 'C,' and 'H' companies, rushed the left of the hill, when the above-mentioned companies of the battalion, led by Captain Venour, assaulted the right. The attack was successful, and the kopje was captured.

During the advance Lieutenants Haskard and Bradford, in command of 'C' and 'H' companies, were wounded, and the engagement cost the regiment nine killed and forty-three wounded. 'D' company, under Lieutenant Ely, towards the close of the afternoon came up on the left of 'H' company, in order to fill the gap between the latter and the Scots Fusiliers.
