Herbert Wrigley Wilson, With the Flag to Pretoria: A History of the Boer War of 1899-1900…
“ The enemy's field artillery opened from Pepworth Hill and Farquhar's Farm upon the British infantry; the British artillery kept under cover and did not reply till the hostile guns, which fired smokeless powder and which were therefore most difficult to find, had been located. Then at last our batteries got to work, and a fierce duel began. The ridge and the plain below were both one sheet of flame. The main Boer artillery position was soon a mass of small clouds of smoke from our bursting shrapnel. ”
