The next day, the allied Afghan militia set up a command-and-control post near the northern gate to direct their tank and mortar fire. By mid-morning they were joined by U.S./British forces divided into three teams: a close air support team designated CAS-1 that went inside the fortress along the bottom of the northeast tower to direct bombing strikes into the southern courtyard, a second close air support team designated CAS-2 that positioned itself near the main gate of the fortress, and a Quick Reaction Force consisting of four more Special Forces troops, a U.S. Navy surgeon, and eight soldiers of the 10th Mountain Division. At 11 pm, a GBU-31 JDAM guided bomb, weighing 2,000 pounds (957 kg), was dropped from an USAF Boeing B-52 Stratofortress, directed by the Air Force Special Tactics combat controller on the CAS-1 team who called in the JDAM strike. The pilot mistakenly punched in the wrong coordinates, hitting the combat controller's position. The bomb's explosion killed 30 allied militiamen and wounded 50 others on the northeast tower above the CAS-1 team, flipped over a friendly tank, and injured all members of the CAS-1 team, including five U.S. and four British operators. That night two AC-130H Spectre gunships (callsigns GRIM 11 and GRIM 14) circled over the fortress, firing at the prisoners. The main ammunition depot was hit, creating a massive explosion which continued to burn throughout the night. One prisoner managed to escape from the fort, only to be captured and lynched by the local population.
