Establishment of Fort Raim While the failure of the 1839 Khivan campaign ruled out long distance punitive expeditions as a tool of control against the southern Central Asians, Russian governors still felt the need to extend control south due to disruption of caravan traffic and challenges to their sovereignty over the Kazakhs. In the 1830s, the
Khanate of Kokand began to expand northward, constructing fortresses to trade, and to collect
zakat from Kazakh herds. Kenesary's Rebellion further disrupted Russian control in the region, and prompted a wave of fort construction in the inner Kazakh steppe.
Fort Raim, built during the rebellion on the mouth of the
Syr Darya at the
Aral Sea, served to control the river and host expeditions. However, the fort's construction worsened Russian relations with Khiva and Kokand. Raiders from the Central Asian states attacked Russian forces, leading to a Russian punitive expedition that expelled a Khivan garrison. Fears of attacks did not lessen, with rumors emerging among Russian regional command of impending attacks on Fort Raim.
Capture of Ak-Mechet By 1852, the Russian administration committed to suppressing Kokand's influence in the region, with the Tsar authorizing a line of forts be constructed to connect the Siberian line to the Syr Darya. The river was seen by the Russian government as a solid line on which to establish a new frontier, and efforts were made to move Russian troops to a sheltered area upstream. However, the commander of
Ak-Mechet, the Kokand Khanate's most influential and critical northern stronghold, warned a Russian surveying party that advancing further along the Syr Darya would be met with force. Vasily Perovsky, serving once again as the Military Governor of Orenburg, responded to these threats by dispatching an expedition to Ak-Mechet under Colonel Blaramberg. The goal of the expedition was to survey Ak-Mechet and possibly destroy the fort under certain circumstances. Blaramberg attempted to attack the fortress upon reaching it, but found his weapons were unable to penetrate the fortress, and retreated at a loss of several men killed and wounded. Russian leadership up to the Tsar himself were alarmed by the failure of Blaramberg's expedition, and resolved to attack again when victory would be certain. In January 1853, the Tsar accepted a plan by Perovsky wherein four forts would be built on the Syr Darya river to establish a stronger, more advanced frontier from which they could influence the southern khanates and protect their territory. While the forts were primarily strategic, Perovsky optimistically argued that protecting caravans and increased tax on Kazakhs would offset the project's enormous cost. One of the fortresses would be built over Ak-Mechet, necessitating a military operation that would also restore Russian prestige after the failure of last year. Perovky's force departed June of that year. A
flotilla and Kazakh camel caravan was used to transport supplies and troops along the Syr-Darya, Kazakhs also providing crucial service as
reconnaissance and guides. Despite the march to Ak-Mechet comprising hot, barren terrain with large swarms of
mosquitos and
horse-flies, the expedition suffered no significant losses. The siege was conducted extremely cautiously, stretching out over several weeks as extensive
mines were dug to avoid a bloody frontal assault. The mines were sprung on the 28th, and after a short Russian assault the fort was captured. While the Russians suffered few casualties, a large majority of the Kokandi defenders were killed, most survivors being women and children.
Khudayar Khan, who had only recently regained power after a coup, lost much of his legitimacy because of the defeat. He sent two expeditions to recapture the fort soon after, both of which were strongly repulsed. Kokand continued to launch small attacks and raids well into the 1860s. The capture of the fort was a seminal point in the Russian conquest of Central Asia. It was the first settlement to be captured by Russia, and the first settlement to have its name
Russified, being renamed to Fort Perovsky in honor of Vasily Perovsky.
Establishment of the line In September 1853, three fortresses named Forts No. 1, 2, and 3 were constructed between Fort Raim and Fort Perovsky, though Fort No. 3 was quickly abandoned. Fort Raim was also abandoned in 1855 due to its redundancy. The forts were intended to become flourishing settlements, serving as military strongholds, trade hubs, and intelligence centers. Fort Perovsky was rebuilt from 1858–1859, though it and the other fortresses suffered from extremely poor building quality, compounded by harsh weather. Logs had to be imported from north of Orenburg, and quickly rotted. As such, many of the buildings were built from
mudbricks, and only lasted for a few years before crumbling. By 1857, Fort Perovsky was surrounded by temporary structures, and inside was filled with collapsed buildings. Sustaining the fortresses was also extremely challenging. Despite hopes to irrigate the land and encourage nomadic Kazakhs to become farmers, grain could not be grown at a rate to sustain even the garrisons, and food had to be imported or purchased at high prices. The fortresses did not become significant centers of trade, located outside of the Russian
customs boundary in the depopulated steppe. Little attempt was made at all to establish a civilian administration, with most efforts focused on collecting intelligence in the region. Russia often questioned cross-country traders to gather generally reliable and timely information on Kokand's military preparations, though information on regional politics tended to be vague. Efforts to curb raids were less effective, groups often successfully captured livestock and caravans, despite punitive expeditions sent out by Russia.
Expansion of the line After Russia's defeat in the
Crimean War and significant victories in the
Caucasian War, the focus of Russian government turned to the security of the Central Asian front. In 1848, a proposal was raised to connect the Syr Darya line to the by advancing south and capturing
Tashkent, ideally establishing a solid border with Kokand and ending the southern raids. After extensive surveys of the
Chu region, a version of this plan in which the Siberian line would be expanded westwards by capturing Kokandi fortresses was approved by the Tsar. There was significant debate on what to do with the Syr Darya line in light of the advances, with proposals being raised within committees and via
memorandums. Ideas included maintaining the status quo, cutting their losses and abandoning the Syr Darya line entirely, expanding along the fertile
Amu Darya to supply the Syr Darya line, and advancing as far as Tashkent. These plans focused on cutting expenses and increasing security, though the best way to do this was highly disputed. == Eastern approach to Central Asia ==
