Three Japanese Kempeitai of Unit 1855 guard eight Chinese prisoners during their forced exposure to frostbite. Unit 1855 was a secret Imperial Japanese Army facility that focused on the development of biological weapons during World War II. It was operated by the Kempeitai, the Japanese military police, with the the headquarters in Beijing. Unit 1855 also operated an experimental branch unit based at Chinan, Hopei. The North China Army established Unit 1855 on February 9 1938. The 2,000 soldiers were housed near Bejing's Temple of Heaven. Headed by Imperial Japanese Army Colonel Yeni Nishimura, he reported directly to Major General Dr. Shiro Ishii of the infamous Unit 731. Unit 1855 killed 1,000 people between 1938 and 1945. Eight male Chinese, aging from 15 to 49, were victims of the experiments carried out from January 31 - February 11, 1941 in Inner Mongolia. The men were exposed outdoors to temperatures of about 27 degrees Celsius below zero with some being deliberately wounded or forced to wear wet shoes and clothing. Unit 1855 recorded the victim's reactions. One teenager became "furious" four minutes after the experiment began, wailed 30 minutes later and could no longer feel his feet after one and half hours. Unit 1855's records claimed the experiments were done to learn how to deal with frostbite afflicting Japanese soldiers during the war. The photo was part of unclassified records titled "Results of Japanese Imperial Army Winter Hygienic Research" discovered in Tokyo in 1995.

Coning Tower Test Using U-2330

Place: Germaniawerft, Hamburg, Germany
Photographer: Unknown

Beginning of March 1945, after the completion of construction, type XXIII submarine U-2330 was lowered by crane onto Slipway 8 of the Germania Shipyard. U-2330 was one of two boats used to test a conning tower variant with an inwards-facing mantle. This variant is easily recognizable by original style of balkon hydrophone array without the later sloped sides. Also clearly visible is the depth sounder opening in the keel. Commanded by Oberleutnant zur See Hans Beckmann, the submarine was attached to the 32. U-Flotille as a training boat from September 1944 until February 1945. It was subsequently assigned to the 11. U-Flotille (Bergen) as an operational boat. The U-2330 did not undertake any sorties, however, and it was scuttled by its crew in Kiel on 3 May 1945. The second Type XXIII boat seen in dock is the U-2323. Noteworthy on this boat are the many handgrip and step recesses on the side of the conning tower and the additional handgrip recesses farther up the rescue float container. The badly-bent starboard forward deflector in front of the forward dive plane may have been caused by a collision with an underwater obstacle or another submarine, or by a too-fast docking maneuver!
