On the night of the 20th of November, three companies of the Rifle Brigade (1st battalion), under Lieutenant Tryon, displayed coolness and courage in a very smart affair. In the rocky ground in the ravine towards the left of our left attack, about 300 Russian infantry established themselves in some caverns and old stone huts used by shepherds in days gone by, and annoyed the working and covering parties of the French right attack and of our advances. These caves abounded in all the ravines, and were formed by the decay of the softer portions of the rock between the layers in which it is stratified. It was found expedient to dislodge them, and at seven o'clock this party was sent to drive the Russians out. The Rifles soon forced the enemy to retreat on the main body, but when the Rifles had established themselves for the night in the caves, they were assailed by a strong column. The action ended in the complete repulse of the Russian columns, but we had to deplore the loss of a most promising and excellent officer, Lieutenant Tryon, who was killed by a shot in the head. Seven men killed and eighteen or nineteen wounded. General Canrobert issued a very flattering _ordre du jour_, in which he especially eulogized the intrepid bravery and noble energy of the three companies of the 1st battalion of our Rifle Brigade in the action, and Lord Raglan mentioned it in very handsome terms. Our army was in a strange condition now. The Light Division was provisionally commanded by Codrington, Sir George Brown being on board the "Agamemnon." The Duke of Cambridge was on board the "Retribution." The Brigade of Guards appeared to be commanded by Colonel Upton. The Brigade of Highlanders was down at Kadikoi, under the command of Sir Colin Campbell. The Second Division was commanded by Brigadier-General Pennefather, in the room of Sir De Lacy Evans, who was on his way home unwell. The First Brigade was under the command of a Lieutenant-Colonel. The Second Brigade was without a brigadier, General Adams' wound was more serious than was supposed. The Third Division was under the command of Sir Richard England, and was fortunate in not being much engaged. The Fourth Division, deprived of all its generals, was commanded by Sir John Campbell. Brigadier-General Lord Cardigan was unable to leave his yacht. The Artillery was under the command of Lieutenant-Colonel Dacres during the absence of Lieutenant-Colonel Gambier, who was wounded, after having succeeded to the command left vacant by the death of Strangways. Our cattle at Eupatoria were by no means in high condition; they perished from hunger. It may readily be guessed that joints from the survivors were scarcely in such a condition as would justify the least conscientious of London waiters describing them as being in "prime cut."
