Note: Companies D, E, and F of the 310th Engineers were not members of the original Polar Bear Expedition, but they did attend Polar Bear reunions after the war.
Almost all of the Polar Bear Expedition manuscript and archival materials held by the Bentley Historical Library, as well as related books and periodicals, have been digitized and are freely available for public use on this website. The library is actively seeking additions to the collections, so some recently-acquired materials are not available online. However, all of these collections are described on this site, and researchers are welcome to contact the library's reference staff regarding access or copies.
