February is a month for celebrating the Shackleton expedition - both Ernest Shackleton and Tom Crean were born in mid February https://www.dib.ie/biography/crean-thomas-tom-a2175 It was also in the month of February that the men and dogs had to abandon ship (although the Endurance continued to drift, and as Patrick Kavanagh wrote in the previous message, didn't sink until Nov.) https://en.wikipedia.org/wiki/Endurance_(1912_ship)
