Tillya tepe, Tillia tepe or Tillā tapa (Persian: طلا تپه‎ ‎ ) or (literally "Golden Hill" or "Golden Mound") is an archaeological site in the northern Afghanistan province of Jowzjan near Sheberghan, excavated in 1978 by a Soviet-Afghan team led by the Greek-Russian archaeologist Viktor Sarianidi, a year before the Soviet invasion of Afghanistan. The hoard is often known as the Bactrian gold.
The Soviets invaded Afghanistan in 1979
The statement says the excavation took place in 1978 a year before the Soviet invasion of Afghanistan. Therefore they invaded in 1979. Difficult to pick up because maybe the system cannot see that 1978 is "a year before" 1979 (which is not mentioned at all)
