In 1920, Bagshawe left his studies to take up an opportunity to join the British Graham Land Expedition to
Antarctica, to continue mapping the western coastline of the
Weddell Sea. As their base, Bagshawe and Lester constructed a hut out of an abandoned whalers' water boat and packing cases. They managed to continue their work, carrying out observations of weather conditions, tidal measurements and studies of penguins, before being picked up by a Norwegian whaling ship in January 1922. Later, the
Bagshawe Glacier, on the
Danco coast of Antarctica, was named after him. == Second World War ==
