The Second Sino-Japanese War
To counteract the Republican advance in Ejen-e, Ma Hongkui then attacked Alashan in 1938. Manchuria Aviation Company workers evacuated to Manchukuo, while the local prince hired coolies to hide the hundreds of canisters of gasoline in a secret chamber of a lamasery. Meanwhile a Japanese caravan carrying gasoline, ammunition, and supplies bound for Ejen-e inexplicably vanished into the Gobi, most likely captured by the Nationalists, with their three Manchuria Aviation Company handlers also sentenced to death in Lanzhou.
