'and' is the link.
(Other definitions for surrender that I've seen before include "submission" , "Cede" , "Yield - release" , "Resign" , "Yield to the control of another" .)
(Other definitions for yield that I've seen before include "Produce, deliver" , "Stop defending" , "bow" , "Chicken out" , "admit defeat" .)
