What happened March 1985 AD

On 10 March 1985 Chernenko died. He led the Soviet Union from 13 February 1984 until his death thirteen months later, on 10 March 1985. Chernenko was also Chairman of the Presidium of the Supreme Soviet from 11 April 1984 until his death.

Became General Secretary of the Communist Party of the Soviet Union

Mikhail Gorbachev was elected General Secretary by the Politburo on March 11, 1985, three hours after predecessor Konstantin Chernenko's death at age 73.

The Iraqis attacked again on 28 January 1985; they were defeated, and the Iranians retaliated on 11 March 1985 with a major offensive directed against the Baghdad-Basra highway (one of the few major offensives conducted in 1985), codenamed Operation Badr (after the Battle of Badr, Muhammad's first military victory in Mecca).

The ferocity of the Iranian offensive broke through the Iraqi lines. The Revolutionary Guard, with the support of tanks and artillery, broke through north of Qurna on 14 March. That same night 3,000 Iranian troops reached and crossed the Tigris River using pontoon bridges and captured part of the Baghdad–Basra Highway 6, which they had failed to achieve in Operations Dawn 5 and 6.

Saddam responded by launching chemical attacks against the Iranian positions along the highway and by initiating the second "war of the cities", with an air and missile campaign against twenty to thirty Iranian population centers, including Tehran.
