The voyage for decade of mine

In 1733, we started expedition which was to explore the east coast of Siberia and to find out if Asia and North America were joined. It took seven years for my groups to cross Siberia. First, we went to Tobolsk. Meanwhile we spent a year in Tobolsk, we built a ship and explored Ob River. Next, we went to Yakutsk and explored the Lena River. After four years, we moved Okhotsk and two years spent there. In the two years of Okhotsk, we built ships so that we could explore and map the east coast. There was problem during the cruise. Many of us were sick from scurvy. Then we started dying. One day, a storm hit our ships and our ship was broken. Finally, we drifted to small island. In small island, we found animal for food and fresh water to drink. However, it was too late for many of us. We continued to die from scurvy. Also, our boss died of scurvy in December 8, 1741. When spring came, we built a small ship from the wood in the old one and left the island.
