Another incident during the war highlighted the question of large-scale Iraqi combat deaths. This was the "bulldozer assault", wherein two brigades from the U.S. 1st Infantry Division (Mechanized) were faced with a large and complex trench network, as part of the heavily fortified "Saddam Hussein Line". After some deliberation, they opted to use anti-mine plows mounted on tanks and combat earthmovers to simply plow over and bury alive the defending Iraqi soldiers. Not a single American was killed during the attack. Reporters were banned from witnessing the attack, near the neutral zone that touches the border between Saudi Arabia and Iraq.[150] Every American in the assault was inside an armored vehicle.[150] One newspaper story reported that U.S. commanders estimated thousands of Iraqi soldiers surrendered, escaping live burial during the two-day assault 24–26 February 1991. Patrick Day Sloyan of Newsday reported, "Bradley Fighting Vehicles and Vulcan armored carriers straddled the trench lines and fired into the Iraqi soldiers as the tanks covered them with mounds of sand. 'I came through right after the lead company,' [Col. Anthony] Moreno said. 'What you saw was a bunch of buried trenches with peoples' arms and things sticking out of them... '"[151] However, after the war, the Iraqi government said that only 44 bodies were found.[152] In his book The Wars Against Saddam, John Simpson alleges that U.S. forces attempted to cover up the incident.[153] After the incident, the commander of the 1st Brigade said: "I know burying people like that sounds pretty nasty, but it would be even nastier if we had to put our troops in the trenches and clean them out with bayonets."[151] Secretary of Defense Dick Cheney did not mention the First Division's tactics in an interim report to Congress on Operation Desert Storm.[150] In the report, Cheney acknowledged that 457 enemy soldiers were buried during the ground war.[150]
