The voyage began as a search for missing men. It became a test of whether a crew could survive long enough to pass from one ocean to the other.
Born in Wexford in 1807, McClure entered the Royal Navy in 1824. He first sailed into Arctic waters aboard HMS Terror in 1836.
In 1850 he sailed westward in HMS Investigator. From Prince of Wales Strait, he established the connection with waters already charted from the east. The ship later became trapped at Mercy Bay. A party from HMS Resolute reached the crew in 1853, and the men returned to Britain in 1854.
McClure later served in China. He was made a Companion of the Order of the Bath in 1859 and became a vice-admiral on the retired list in 1873.
Sherard Osborn shaped McClure’s journals into the account published in 1856. Its changes of pace follow the work of the expedition, from sounding and charting new waters to rationing supplies while the ship lay still.
The expedition completed the first recorded traverse of a North-West Passage. Its course is best followed in stages, from the Pacific approach to the journey across the ice and the return through eastern Arctic waters.
