Published posthumously in 1889, this journal records the 1850-5 expedition undertaken by naval officer and navigator Sir Richard Collinson (1811-83) to attempt to discover the fate of Sir John Franklin's expedition by entering the hypothetical North-West Passage from the 'other side', via Bering Strait. Franklin, the famous Polar explorer, disappeared on an expedition to discover the Passage in 1845, and no fewer than thirty attempts were made between 1847 and 1859 to investigate what had happened to his 129-strong party. Collinson set out in command of HMS Enterprise in 1850, and his ship, which passed three successive winters in the Arctic, came closest to the place where Franklin's expedition was believed to have ended. Collinson was awarded a Gold Medal by the Royal Geographical Society in 1858 for making a significant contribution to the geographical knowledge of the area, and he was knighted in 1875.
