The servicemen who successfully completed the war-time courses in Japanese at School of Oriental and African Studies (SOAS) were instructed to assemble at the intelligence training unit in Wentworth, three miles north of Sheffield. Colonel Wards had a thorough knowledge of Japanese army organisation and training, spoke the language and understood the Japanese. The British were ready for the Japanese offensive and on 13 February mounted a general assault by land, sea and air, rushing in 25th and 36th Indian Divisions from land. The Japanese tightened the net but could not take Sinzweya and were forced to withdraw. The British Indian Army obtained Japanese documents from various sources at the front line. The Japanese Army encouraged the writing of diaries when servicemen were stationed in Japan. Soldiers who returned to Japan after being taken prisoner in the Russo-Japanese War appeared before an inquiry in 1906.
