Duncan Sloss, the Vice Chancellor of the University of Hong Kong, is taken from camp to the French Hospital for X-rays. Most people on this scheme spend only a day or two in the hospital, but Sloss is kept there until November 21 because of stomach problems.
During his stay he becomes involved in a British Army Aid Group plan to negotiate the repatriation of Stanley's mothers and children (the plan is code-named 'Milkers and Calves'). The intermediary used by the BAAG is Irish Jesuit priest Gerard Casey, who knew Sloss because he used to teach Geography at the University (hence his code name 'Geographia').
