Operation Crimp also known as the Battle of the Ho Bo Woods—was a joint US-Australian military operation during the Vietnam War in the Ho Bo Woods, north of Cu Chi in Binh Duong Province, South Vietnam, between 8–14 January 1966. January 28 – March 6 Operation Masher was a combined U.S., ARVN, and ROKA operation that began on January 28, 1966. The name "Operation Masher" was changed to "Operation White Wing", because the name was deemed too crude for 'nation-building'.
