Read endurance. This is the most impressive survival feat and example of true leadership, every - single - one of his crew survived... The dude converted a large row boat into a sea going vessel and crossed the worst seas in the world just to get to elephant island (100+ miles? Away) - only to have to mountaineer without gear over a mountain to get to a whaling station. But not just mountaineering, they got up into the mountains only for a terrible snow storm start to stir up... They then used frozen rope as a sled.... Man read the book, it's like jaw dropping... Not based on a true story - shit is a true story
