But the main features of the contest are fairly clear. The Russians, securely posted in the Quarry Ravine, St. Clement’s Gorge, and on the eastern slopes of the Kitspur, made their main attack against the latter, and as their assaulting columns were driven from the crest, they rallied again in the hollows beneath, and kept surging upwards, and renewing the strife. For some time the Brigade drove back the successive waves of the advancing enemy unassisted, except by the broken fragments of Adams' men; but a little later, when Cathcart’s division approached, some 500 of his troops were pushed forward, and joined in the fray, while another portion moved to the head of the Quarry Ravine, and regained the Barrier. The latter, reinforced from time to time, remained there during the rest of the battle, and though the enemy passed them by, now as he advanced and again as he retired, it seems he never closed in on their rear or reconquered the post. Colonel Upton, reaching the ground some time about 8 a.m., with No. 5 company and a company of the Scots Fusilier Guards, also coming off piquet,[281] endeavoured to close an undefended gap which existed between the Sandbag battery and the Barrier, and he prevented the enemy from seizing its advantages at that moment. But his force was insufficient to hold it for more than a brief space, and his men were most of them drawn into the vortex of the principal fight. Hence, it was not difficult for the Russians, pressing through the gap, to work round the left flank of the Brigade, and to penetrate to their rear. Most of the Fourth Division, having been split up into fractions, were sent wherever the pressure of the battle required their presence; but a residue of 400 men under General Torrens remained, and with this force Cathcart hoped to relieve the Brigade in their arduous struggle, and assail the enemy in flank by descending the slopes on our right. The attempt, though successful at first, was not fortunate, and it failed to accomplish the results that were expected from it. The men soon dispersed in groups, were almost surrounded, and had to fight their way upwards with the Russians above them. It was here, moreover, that the valuable life of Cathcart was lost, and that Torrens (some time in the Grenadier Guards) was severely wounded. ----- Footnote 281: It appears that No. 4 company moved forward separately, and joined the main body of the Battalion. -----
