Operation Dawn-1 was an Iranian offensive in the Iran–Iraq War. On April 10, 1983, Iran struck Ein Kosh with the immediate objective of Fuka (east of al-Amarah) to capture the Baghdad-Basra Highway. The operation was fought moslty by Pasdaran forces and was one of the three costly human wave offensives of 1983, although despite heavy losses on both sides the operation failed to defeat the Iraqis.
