(CNN) -- It was a frigid June night at Pickstone Mine in Zimbabwe when 67-year-old Angela Campbell -- soaking wet, her arm broken and a gun to her head -- signed a document vowing to give up the fight for her family's farm. Angela Campbell, 67, was beaten and kidnapped days after Zimbabwe's runoff election. The kidnappers demanding her signature at gunpoint were "war veterans" from President Robert Mugabe's heyday as a liberation hero, and they made it clear that her refusal would mean more beatings. Though Campbell signed the document, her son-in-law said she has no intention of giving up her battle; Campbell's family will be in Windhoek, Namibia, on Wednesday to present arguments to a Southern African Development Community tribunal.
