"The Turkish-Egyptian garrison of Eupatoria, reduced to one division by the departure in spring of Omer Pasha to the allies' camp in front of Sevastopol, was successively reinforced during the course of the summer months so that at the beginning of September it was composed of 24 battalions (of which 12 were Egyptian), some squadrons of irregular cavalry, 3 regiments of regular cavalry, and 5 field batteries, totaling 20,000 men under the overall command of Achmet Pasha. The commander of the Egyptian division was Soliman Pasha.
A short time after the capture of Sevastopol, Marshal Pélissier had General d'Allonville's cavalry division leave the Baidar valley. He ordered it to embark for Eupatoria to force the Russian troops established in front of that place to withdraw so that they would not be able to directly threaten its garrison. As soon as this was accomplished, the cavalry division was to deploy so as to fall on the road to Perekop. The troops sent to Eupatoria consisted of the 4th Hussar Regiment and all of General Champeron's dragoon brigade (6th and 7th Regiments), to which cavalry force were added a horse-artillery battery and six Turkish battalions which had been in Balaklava under the command of Sefer Pasha.
All of the allied forces in Eupatoria were placed under General d'Allonville who disembarked there on 19 September [1855] and reviewed the Turkish troops on the 20th. On 24 September he made a reconnaissance towards Sak, convincing himself that there was no fear of an attack from that direction, and on the 29th he successfully began his operations in the area northwest of the town. This was an advance in three columns. The one on the right, commanded by Soliman Pasha and consisting of six battalions, some irregular cavalry, and one battery. Its marching orders were to go toward Sak in order to contain any attack attempted by the Russians from this side. The center column was under the command of General d'Allonville and was made up of three French cavalry regiments, 200 mounted Turks, a horse-artillery battery, and six Egyptian battalions. This column took advantage of a stony ford to cross an arm of Lake Sassik and marched to Djoltchak via Chibar. Meanwhile, a left column made up of twelve battalions, three cavalry regiments, and two batteries, all commanded by Achmet Pasha, followed the road to Oraz, Altchin, and Tejech and was to meet up again with General d'Allonville's column in Djoltchak. The column which advanced toward Sak only encountered before this place some squadrons which it easily contained with the help of two gunboats that could bombard the areas next to the lake
