Robert F. Scott in Antarctica

Robert Falcon Scott led two expeditions to Antarctica; the expedition records for both are available on Internet Archive.

Scott wrote the expedition record for the first after he returned to Britain in 1904.

The Voyage of the 'Discovery', 1905

The second expedition (Terra Nova) began in 1910. He died in March 1912 in Antarctica. The expedition record was arranged by Leonard Huxley and published in 1914. Volume 1 provides the journals of Scott and Volume 2 provides the reports of the journeys and the scientific work undertaken by Dr. E.A. Wilson (who died with Scott) and the surviving members of the expedition. Both volumes are illustrated by photographs taken by Herbert G. Ponting (the first professional photographer included in an Antarctic expedition) and other members of the expedition. There are also a few color plates and sketches made by Dr. Wilson.

Scott's last expedition V1, 1914

All three books are well worth browsing. The pictures/illustrations prompt some reading as well. These are as close as it gets to firsthand descriptions of what happened.
