For various reasons, I missed putting up the Anglo Soviet invasion of Iran when it occurred. It commenced on August 25, 1941.

On this day, it concluded with a ceasefire. The country would be occupied by the British and the Soviets for the remainder of World War Two.

The Iranian military did resist, but ineffectively. The country would be occupied by the British and the Soviets throughout the war, with the British withdrawing on time in March 1946 but the Soviets refusing to do so, citing security concerns. A complaint to the United Nations from Iran on this became the first such complaint filed with that then newly founded body. The Soviets withdrew in May, 1946.

Ultimately Iran became an Allied power and declared war on Germany. The US contributed to the forces in Iran during the occupation, which assuaged Iranian fears of being absorbed as a colony by the occupying powers. The Soviets did sponsor Communist groups that did create problems for the Iranian government, so it cannot be claimed that the occupation was wholly benign.
The Soviets launched a major counterattack near Smolensk which was successful, as to its objectives, but which sustained high casualties. The Germans also sustained high casualties.
The British conducted the first of two small nighttime commando raids on the Pas-de-Calais.
