In early 1978, Henry and partner Rob Taylor attempted the first ascent of the Breach Wall on Mount Kilimanjaro in Tanzania. Taylor fell while leading steep ice, and broke his ankle very badly. The details of what happened following the accident vary depending on which of the two parties is telling the story. Barber's party says that Barber helped Taylor descend; got him to a hospital; and then left to fly back to the United States to keep a speaking commitment. Taylor's party says that Barber abandoned him on the mountain, forcing him to climb down alone with his leg mangled. He somehow reached the rainforest at the base of the mountain and was rescued by local tribesman. Taylor nearly lost his leg at the hospital, and felt abandoned by his partner. After he recovered, Taylor wrote articles and a book (The Breach, Putnam, 1981) painting Barber in a very unflattering light.
