Then, the course was against a boiling torrent. Thirty men could not tug a boat up the Yudoma. They stood in ice-water up to their waists lifting the barges over the turbulent places. Sores broke out on the feet of horses and men. Three years it took to transport all the supplies and ships' rigging from the Lena to the Pacific, with wintering barracks constructed at each stopping place.
It was the end of June, 1735, before the main forces were under way again for the Pacific. From Yakutsk to Okhotsk on the Pacific, the course was down the Lena, up the Aldan River, up the Maya, up the Yudoma, across the Stanovoi Mountains, down the Urak river to the sea. A thousand Siberian exiles were compelled to convoy these boats.
