As 1984 began, Iran
launched the largest offensive up to that date Operation Dawn V
, also known as Operation Dawn 5
or Operation Valfajr-5
). The goal of the offensive was to split the Iraqi
4th Army Corps and 6th Army Corps between Basra
, and if successful, move on the suburbs or even the city of Basra itself. It was fought between the Pasdaran
and the Iraqi Army
. In the early phase, a force of an estimated 100,000-150,000 Pasdaran and Basij, using small motorboats and then on foot moved towards the objective, then attacked using human wave tactics and in places came within a few kilometers of the strategic Basra–Baghdad highway
. However the Iranians
lacked artillery, air support and armored protection, while the Iraqis were well equipped and entrenched in strong fortified positions.
The armies inflicted severe casualties on each other and the Iranians
failed to achieve their objective. This operation was the biggest of the Dawn operations.
