By the early 1640s, Yakutsk on the Lena River was a key Russian outpost for collecting yasak (fur tribute) and launching Cossack-led exploration deeper into eastern Siberia. Russian officials and Cossacks used the region’s river networks as “highways” to push toward new lands and resources. This frontier setting shaped the decision to probe routes south toward the Amur basin.
In July 1643, Yakutsk voevoda (military-governor) Pyotr Golovin sent Vasily (Vassili) Poyarkov south with about 133 men and supplies for travel and trade. The goal was to investigate the Zeya and Amur river regions and assess their people and resources. This decision tied exploration directly to state interests and future conquest planning.
Poyarkov’s force set out from Yakutsk in mid-1643, traveling up the Lena River and then into tributaries leading toward the Stanovoy Range. The expedition relied on boats where possible, but also faced long portages (overland carries) between river systems. The difficult logistics foreshadowed major losses later in the journey.
Moving up the Aldan and then smaller rivers, the party encountered numerous portages—reported as dozens—through rough terrain. These delays pushed the expedition into early winter conditions near the Stanovoy watershed. Time lost here mattered because it reduced food supplies and narrowed safe travel windows.
In December 1643, Poyarkov pushed south over the mountains toward the upper Zeya River, entering Daur lands (often called Dauria). He encountered settled farming communities connected to wider trade networks, including Chinese goods, and linked to Manchu power. This confirmed Russian hopes that the Amur basin could support settlement and revenue, not only fur extraction.
During the winter of 1643–1644, Poyarkov built a small winter fort near the Zeya (described near the mouth of the Umelkan). Accounts describe harsh methods used to force supplies from local people, which helped trigger resistance and made resupply harder. Starvation and violence devastated the detachment and shaped how later Amur communities reacted to Russian arrivals.
By spring 1644, the expedition had suffered severe losses, and surviving groups reunited and moved down the Zeya into the Amur. As they traveled, they faced ambushes and hostility, reportedly intensified by earlier abuses. The descent nonetheless provided the first sustained Russian passage from the Lena basin to the Amur system.
By late 1644, the expedition reached the lower Amur near its mouth, where Russians used the name “Gilyak” for the Nivkh people. This phase expanded Russian geographic knowledge from inland river routes to the Amur estuary and coastal zones. It also set a pattern of contact and conflict that later expeditions had to manage.
The expedition overwintered in the lower Amur/Okhotsk Sea region in 1644–1645, positioning itself to attempt a coastal route north. Spending a second winter was a turning point: it shifted the mission from river exploration to a risky sea-and-coast return route. This choice aimed to avoid retracing the most punishing inland portages immediately.
In the summer of 1645, Poyarkov’s survivors moved along the Sea of Okhotsk coast, aiming for known landmarks used by earlier Russians. Coastal travel connected Amur exploration with the emerging Russian presence on the Okhotsk shore. This helped demonstrate a broader “arc” of routes from Yakutsk to the Pacific edge.
By 1646, Poyarkov reached the Ulya River area, reusing earlier Russian huts associated with Ivan Moskvitin’s 1639–1640 coastal explorations. This waypoint mattered because it linked the Amur expedition to a growing chain of Russian travel stations on the Sea of Okhotsk side. It also made the final return to Yakutsk more feasible.
In summer 1646, Poyarkov returned to Yakutsk with only a fraction of his original party alive, but with firsthand information about the Zeya–Amur corridor and its peoples. His results encouraged later, larger armed ventures—especially Yerofey Khabarov’s expeditions—because officials now had a rough route and a clearer sense of what could be taken and contested. As a closing outcome, Poyarkov’s journey marked the beginning of sustained Russian campaigns toward the Amur, which later escalated into wider Qing–Russian frontier conflict.
