At dusk a handful of officers and men succeeded in making their way to the Scots Guards' machine gun which had been silenced in the morning, and brought it back, together with one or two wounded men of the detachment who lay around it. At intervals during the day the British right flank was annoyed by shots from Boers on the plain to the east of the Riet. These men several times appeared to be about to make a serious attack upon this part of the line, but their purpose always withered up under the fire of the Grenadiers' Maxim gun, of detachments of the Guards left to hold the southern reservoir, and of the mounted infantry and 9th Lancers on the extreme right rear. [Sidenote: Grenadiers and 2nd Coldstream move at 7 a.m., Nov. 28th, straight for river east of bridge.] [Sidenote: They are stopped at 1,000 yards from it.] When the Scots Guards commenced their turning movement, the Grenadiers and the 2nd battalion of the Coldstream began their frontal attack, and arrived within 1,000 or 1,100 yards of the enemy who lined the river bank.[175] At this range the hostile fire was so severe that it became impossible to get nearer and, as the day wore on, the difficulty of keeping the men supplied with ammunition grew more and more serious. When night put an end to the engagement, in many companies the soldiers had but ten cartridges left in their pouches with which to cover an attack, or repel a counter-stroke. So long as the men lay flat on the ground they were little molested, as a growth of thistles hid them from the enemy's view, but any attempt to move brought upon them a shower of bullets, to which they were unable to reply with any effect, as the Boers, perfectly protected by their trenches or concealed by the vegetation which lined the river bank, suffered little from the shrapnel of the supporting British guns, and could not be seen by the infantry. [Footnote 175: A few groups of officers and men were able to win their way three or four hundred yards nearer to the Boer defences, but with heavy loss.] [Sidenote: 18th and 75th batteries support Guards.] [Sidenote: Naval guns engage Boer guns.]
