During the morning, while the Russians were taking the earthworks along the ridge, our two cavalry brigades, in the words of General Hamley, had been manoeuvring so as to threaten the flanks of any force which might approach Balaclava, without committing themselves to an action in which they would have been without the support of infantry. Ultimately, until his infantry should become available, Lord Raglan drew in the cavalry division to a position on the left of redoubt No. 6, near the foot of the Chersonese upland. While it was temporarily quiescent there Liprandi was engaging in an operation of enterprise rare in the record of Russian cavalry. General Ryjoff at the head of a great body of horse started on an advance up the North valley. Presently he detached four squadrons to his left, which moved toward where Sir Colin Campbell was in position at the head of the Kadiköi gorge, was repulsed without difficulty by that soldier's fire, and rode back whence it had come. The main body of Russian horse, computed by unimaginative authorities to be about 2000 strong, continued up the valley till it was about abreast of redoubt No. 4 [Footnote: See Map.], when it halted; checked apparently, writes Kinglake, by the fire of two guns from a battery on the edge of the upland. The "C" Troop chronicler states that in addition to "a few" shots fired by this battery (manned by Turks), the guns of "I" troop R.H.A., temporarily stationed in a little hollow in front of the Light Brigade [Footnote: See Map.], fired rapidly one round each, "haphazard," over the high ground in their front. General Hamley assigns no ground for the Russian halt, but mentions that just at the moment of collision between our Heavies and the Russian mass "three guns" on the edge of the upland were fired on the latter. From whatever cause, the Russian cavalry wheeled obliquely to the leftward, crossed the Causeway heights about redoubt No. 5, and began to descend the slope of the South valley. Kinglake heard of no ground for believing that the Russian horse thus wheeling southward, were cognisant of the presence of the Heavies in the valley they were entering. But the "C" Troop chronicler states that as the Troop was crossing the plain a few Russian horsemen were seen by it trotting fast along the top of the ridge [Footnote: See Map.], who, when almost immediately afterwards the head of the Russian column showed itself on the skyline, were set down as the General commanding it and his staff.
