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 
786.

Passage: The Tepehuán suffered a series of devastating epidemics of European-introduced diseases in the years before the revolt. Epidemics were known to have occurred in their region in 1594, 1601-1602, 1606-1607, 1610, and 1616-1617.  The Tepehuán and their neighbors may have been reduced in population by more than 80 percent by the epidemics, from a pre-Columbian population of more than 100,000 to fewer than 20,000,  of which the Tepehuán may have been one-half of this total During the Chichimeca war  the Tepehuán remained neutral although urged by the Chichimecas to join them in resistance to Spanish expansion. The Spanish failed to defeat the Chichimeca militarily and instituted a new policy called "peace by purchase" in which Catholic missionaries would be a major tool in pacifying hostile and semi-hostile Indians.  Indians were to be supplied with food and tools and resettled into towns. Missionaries, rather than the military, would take on most of the responsibility for integrating the Indians into Mexican and Christian society.  The Acaxee and Xixime were the first to have this new Spanish policy applied to them and the Tepehuán would be next. 
Question: How many years was there in between the first year where epidemics were known to have occurred and the last year? 
Answer type: Number 

23.
