to free Belgica, they quickly realised that they would be trapped for the duration of the Antarctic winter. Winter The Belgica expedition was poorly equipped and did not have enough winter clothing for every man on board. There was a shortage of food, and what there was lacked in variety. Penguins and seals were hunted and their meat stored before the onset of winter left the region devoid of wildlife. Warm clothing was improvised from the materials available. On 21 March 1898, Cook wrote: "We are imprisoned in an endless sea of ice ... We have told all the tales, real and imaginative, to which we are equal. Time weighs heavily upon us as the darkness slowly advances." Several weeks later, on 17 May, the perpetual darkness of polar night set in, and lasted until 23 July. Gerlache disliked the penguin and seal meat that had been stored and initially tried to ban its consumption, but eventually encouraged it. Signs of scurvy began to show in some of the men. Gerlache and Captain Georges Lecointe became so ill they wrote their wills. Two of the crew started to show signs of mental illness and morale in general was extremely poor. Lieutenant Danco fell ill from a heart condition and died on 5 June. Danco Island was named in his honor. Several men reportedly lost their sanity at this point, including one Belgian sailor who left the ship "announcing he was going back to Belgium." Cook and Amundsen took command as Gerlache and Lecointe were unable to fulfill their roles due to scurvy. The true cause of scurvy as a deficiency of Vitamin C was not discovered until the 1920s, but Cook was convinced that raw meat was a possible cure for scurvy due to his experiences with Robert Peary in the Arctic. He retrieved the frozen penguin and seal meat and insisted that each man eat some each day. Even Gerlache began to eat the meat and slowly the men recovered their health. It is now known that raw meat and organs contain a small amount of Vitamin C. Several months of hardship followed. Even as spring and summer arrived, attempts to free the ship and its crew from the grip of the ice failed. By January 1899, Belgica was still trapped in ice about thick and the possibility of another winter in the ice seemed real. Open water was
