Operation Fajr al-Nasr (Before the Dawn/Dawn of Victory), launched on 6 February 1983, and it saw the Iranian shift of focus from the southern to the central and northern sectors. Iran, using 200,000 "last reserve" Revolutionary Guard troops, attacked along a 40 kilometres (25 mi) stretch near
Al Amarah, Iraq about 200 kilometres (120 mi) southeast of Baghdad. One armoured division proceeded to
Sumar in the central zone as a diversion to mask seven reserve infantry divisions that went from the southern sector to the central city of Dezful. The Iraqis knew about this concentration of forces and knew that an inevitable mass human wave assault would occur in the central zone, yet did nothing to disrupt what would be Operation Before the Dawn, which began in February 1983.[64] This was Iran's long-awaited plan to take the war inside Iraq on a grand scale. The Iranians wanted to penetrate and capture the cities of al-Shabeeb and al-Amarah, and to reach the highways linking
Baghdad down to Amarah and further down to Basra. In the south, a massive Iranian force of two
infantry and two armoured divisions, three border guard regiments, an airborne regiment, a Basij division, and two artillery battalions attempted to isolate Basra from the rest of Iraq.[64] Facing the Iranians was the Iraqi 4th Corps, which was made up of two infantry divisions, one mechanized division, and two armoured divisions. The al-Shabeeb assault was stalled by 60 kilometers of hilly escarpments, forests and river torrents blanketing the way to Amarah. Once the Iranians finally arrived near Amarah, Iraqi air force fighters thwarted Iranian close air support, but the Iraqi counter-attack was also hindered and the various attacks and counter-attacks regressed into entrenchment and
artillery duels. The Iranians dug themselves in along the entire front lines, from north to south, and although Iraq countered the assault on al-Shabeeb, it did not result in Iraq's tactical advantage as these thousands of entrenched Iranian forces now concentrated artillery fire on
Basra, Khanaqhin, and
Mandali.[64] By the middle of the offensive, Tehran Radio reported having liberated over of Iranian territory (which in fact was one of several disputed territories). The reality was much more bleak, however, as Iran continually resorted to crude tactics, including the use of soldiers in
human wave charges across
no man's land, which was always met with withering fire from the Iraqis. Lightly equipped, inadequately supported, and poorly trained Iranians attempted to charge dug-in Iraqi infantrymen firing from trenches. In addition, Iranian teenage soldiers died by the hundreds, and some were captured after being wounded. Residents of the city of
Ahvaz, behind the front, reported that their morgue was filled to the rim with bodies from the field. ==Personal account==
