It was very difficult to discover the Boer positions. There was one long trench near the kraal which the naval guns had been shelling, and further to the west could be seen another parapet from which came an occasional puff of smoke betraying a Martini rifle and black powder. But if the Boers could not be seen, they could be both heard and felt. There was one ceaseless rattle of mausers, and a constant hum of bullets only drowned by the scream of the shells. [Illustration: Casualties at Colenso. Capt. BACON. _Killed._ Lieut. HENRY. _Killed._ Capt. H. M. SHEWAN. _Wounded._ Major GORDON (_1st Battalion, attached_). _Wounded._ Second Lieut. MACLEOD (_1st Battalion, attached_). _Wounded._] Short rushes were made as a rule, and the flank companies edged away in order to give room for a more reasonable extension. But no sooner had the battalion opened out than it was reinforced by companies of the Connaught Rangers, and, later, of the Inniskilling Fusiliers and the Border Regiment. In a comparatively short time, after the first Boer shell, the 5th Brigade had been practically crowded into one line. Officers led men of all the four regiments, and encouraged them with the cry, 'Come on, the Irish Brigade!' There was no control, no cohesion, no arrangement in the attack. No attempt was made to support, by the careful fire of one part of the line, the advance of the remainder; nor did any order from the higher ranks reach the firing line. Small groups of men, led by an officer, jumped up, dashed forward a few scores of yards, and then lay down. Nobody knew where the drift was, nobody had a clear idea of what was happening. All pushed forward blindly, animated by the sole idea of reaching the river-bank. On the left, part of the battalion was almost on the river when the Boers first opened fire, and quickly reached the bank. After a short halt they turned to their right and moved in single file along the river, being exposed all the time to a heavy fire. They passed through a kraal, and eventually, not being able to find the drift, assembled in a hollow, where they stayed until orders to retire reached them. The centre and right advanced through low scrub into a loop of the river. Some sections of the 1st Battalion, on the extreme right, came upon a spruit, and, under shelter of its banks, pushed ahead of the line. Thus, by short and constant rushes, the assailants worked their way forward. A brigade of field artillery was supporting the attack from behind, but they found it as difficult as the infantry did to locate the Boers, and most of their shells were quite harmless to the enemy, while a few dropped close to the attacking infantry. They aided the latter indirectly, however, since the Boer guns turned their attention to them.
