Operation Bloodhound, later renamed Operation Bushmaster II, commenced on 1 December when the
2nd Battalion, 2nd Infantry Regiment (2/2nd Infantry) was landed at Landing Zone Dallas () inside the Michelin Rubber Plantation. LZ Dallas was to serve as the command post for the two Battalions involved in the operation. From 2–5 December the US Battalions searched southeast of LZ Dallas in the VC base area known as the
Long Nguyen Secret Zone. By 14:30 the VC begun withdrawing, leaving behind their dead and wounded. Shuffer decided not to pursue the retreating VC fearing a further ambush and withdrew into a night perimeter. The 2/2nd Infantry spent the next few days policing the battlefield and destroying bunkers and Operation Bushmaster II ended on 6 December. ==Aftermath==
