The 334th deployed from Asadabad on foot at 10:00 p.m. on April 20, crossing the Kunar River by ferry. The plan was straightforward: 1st Company would advance through the narrow gorge floor toward Sangam while 2nd and 3rd Companies provided cover from the ridges above. By 5:00 a.m., 1st Company had entered Sangam and searched it without finding resistance. But two mujahideen were spotted retreating deeper into the gorge. Major Terentyev, commanding from near the gorge entrance, ordered their capture. Captain Tsebruk, leading 1st Company, divided his men into four platoons and pushed toward Daridam, a settlement two kilometers further in. They moved along the gorge floor without flank cover from the ridges -- a decision that would prove fatal. Only the 3rd Company commander, positioned atop the ridge above Sangam, had a clear view of what was unfolding ahead.

Lieutenant Nikolai Kuznetsov's platoon made first contact with hostile fighters. Captain Tsebruk immediately moved toward the gunfire with four riflemen, leaving his radio operator behind. It is believed he grasped the severity of the situation, but before he could act, a bullet struck him in the throat. He died where he fell. With Tsebruk gone, Major Terentyev lost control of the battle. The mujahideen sprung their ambush with devastating precision -- using buses to circle behind 1st Company and block its retreat, while heavy machine guns emplaced on both ridges pinned down the 2nd and 3rd Companies above. The trap was complete. Cut off and surrounded, 1st Company's soldiers took cover behind low mud walls, firing until their ammunition ran out within minutes. Some lit orange smoke grenades, the signal for air rescue. No aircraft came in time.

Back at Asadabad, the base scrambled to assemble an armored relief column. But the geography that made Maravar Gorge a perfect ambush site also made rescue nearly impossible. The heavy vehicles could not fit on the local ferry, forcing the column to cross the Kunar River via a bridge 10 kilometers away, then drive 13 kilometers back toward the gorge. A straight-line distance of three kilometers became a 23-kilometer grind across rugged, mine-seeded terrain. Of the entire armored column, only a single BMP infantry fighting vehicle reached Maravar Gorge that morning. It arrived too late to save 1st Company in Daridam, though it may have prevented the destruction of the 2nd and 3rd Companies, now under heavy attack in Sangam. When the full column finally arrived that afternoon, exhausted survivors stumbled out carrying their wounded and their dead.

Reinforcements poured in from across the region. The 154th Spetsnaz detachment and the Air Assault Battalion of the 66th Brigade flew in by helicopter from Jalalabad. The 2nd Battalion of the 66th Brigade marched overland from Asadabad. What the 334th's commanders had planned as a training exercise now involved four battalions and frontline aviation units fighting across mountainous terrain. The mujahideen did not simply flee. They fought for two more days, covering the exodus of civilian refugees from Sangam and Daridam toward Pakistan. Three more Soviet soldiers died during the follow-on operations. The 334th had been in Afghanistan for less than a month. The unit had deployed from Mariansky Gorki in the Belorussian Military District -- green troops, newly arrived, thrown into terrain that rewarded experience and punished overconfidence.

The villages of Sangam and Daridam sit in the same volatile borderlands of Kunar Province that would see intense fighting for decades to come. Twenty-five years after the Soviet Spetsnaz walked into Maravar Gorge, American and Afghan National Army forces fought the Taliban near the same location during Operation Strong Eagle in 2010. The geography has not changed -- narrow gorges channeling movement into kill zones, ridgelines offering commanding fields of fire, and a population that has outlasted every foreign army to enter these mountains. The Battle of Maravar Pass endures as a case study in what happens when assumptions meet reality in Afghan terrain: the enemy was not eight to ten fighters in a village. The gorge was not a training ground. And three kilometers, in these mountains, is never just three kilometers.
