right, they were attacked from Diamond Hill. A section of Q Battery RHA attempted to return artillery fire, but had no infantry support, until the 12th Lancers arrived on the front line. Lord Airlie took 60 men to clear the Boers from the guns, and in the ensuing exchange of rifle fire at short-range, Lord Airlie was killed. The Boers pressed the matter hard. Two squadrons of the Household Cavalry Regiment and one squadron of the 12th Hussars charged at full gallop at Boers firing from concealed positions. The enemy dispersed. Following the indecisive results of 11 June, Roberts decided to make a frontal attack on the next morning. The morning of 12 June with artillery fire from guns escorted to forward positions by a squadron of New South Wales Mounted Rifles led by Captain Maurice Hilliard, allowing a Regular infantry advance that captured Diamond Hill. A counterattack was planned by Botha, supported with fire from Rhenosterfontein Hill.

Among those killed in the attack were Lieutenants Percy Drage and William Harriott of the New South Wales Mounted Rifles. On the morning of 13 June De Lisle's corps pursued the retreating Boers until they expended their ammunition and received artillery fire in return. Aftermath On 13th the Botha's army retreated to the north, they were chased as far as Elands River Station, only 25 miles from Pretoria, by Mounted Infantry and De Lisle's Australians. Although Roberts had removed the Boer threat to his eastern flank, the Boers were unbowed despite their retreat. Jan Smuts wrote that the battle had "an inspiriting effect which could scarcely have been improved by a real victory." Forty-four years after the battle, British General Ian Hamilton opined in his memoirs that "the
