Passage: On 25 June, Iraq launched the second Tawakal ala Allah operation against the Iranians on Majnoon Island. Iraqi commandos used amphibious craft to block the Iranian rear, then used hundreds of tanks with massed conventional and chemical artillery barrages to recapture the island after 8 hours of combat. Saddam appeared live on Iraqi television to "lead" the charge against the Iranians. The majority of the Iranian defenders were killed during the quick assault. The final two Tawakal ala Allah operations took place near al-Amarah and Khaneqan. By 12 July, the Iraqis had captured the city of Dehloran,  inside Iran, along with 2,500 troops and much armour and material, which took four days to transport to Iraq. These losses included more than 570 of the 1,000 remaining Iranian tanks, over 430 armored vehicles, 45 self-propelled artillery, 300 towed artillery pieces, and 320 antiaircraft guns. These figures only included what Iraq could actually put to use; total amount of captured materiel was higher. Since March, the Iraqis claimed to captured 1,298 tanks, 155 infantry fighting vehicles, 512 heavy artillery pieces, 6,196 mortars, 5,550 recoilless rifles and light guns, 8,050 man-portable rocket launchers, 60,694 rifles, 322 pistols, 454 trucks, and 1,600 light vehicles. The Iraqis withdrew from Dehloran soon after, claiming that they had "no desire to conquer Iranian territory." History professor Kaveh Farrokh considered this to be Irans greatest military disaster during the war. Stephen Pelletier, a Journalist, Middle East expert, and Author, noted that "Tawakal ala Allah … resulted in the absolute destruction of Irans military machine.". 
Question: How many more tanks were captured by the Iraqis in March than heavy artillery pieces? 
Answer type: Number
