does anyone know which date (exactly) the crew abandoned the endurance and which date it sank I have searched on the internet have have two different dates for both.
Not very impressed with your searching ability Mickey, first page that comes up if you type Shackleton into google is http://www.pbs.org/wgbh/nova/shackleton/
if you click the expedition timeline it takes you to http://www.pbs.org/wgbh/nova/shackleton/1914/timel ine.html
which shows that as drochit says Shackleton gave the order to abandon the Endurance at 5pm on October 27th and that they watched the boat sink on 21st November 1915 along with a wealth of other information.
