04/04/04 The siege of Sadr City
The siege began on 4 April 2004 – later dubbed "Black Sunday"– with an uprising against the Coalition Provisional Authority following the government banning of a newspaper published by Muqtada Al-Sadr's Sadrist Movement. On April 4, militiamen ambushed a 1st Cavalry Division patrol and Iraqi police were expelled from three police stations in Sadr City. Members of the newly arrived 1st Cavalry Division and elements of the 2nd Armored Cavalry Regiment were sent out to retake them. Eight US troops were killed and 51 more wounded in the bloody battle.
