<DIV><DIV>This diary of&nbsp;Leonard Wood, a&nbsp;medical officer, tells the dramatic story of the last campaign against the Apache chief Geronimo. It is the only journal kept by anyone on that expedition.<DIV>&nbsp;<DIV>Under the command of Capt. Henry Lawton, Wood&#8217;s first field duty was to pursue Geronimo on a hard-driving chase from Arizona deep into Old Mexico. Although this expedition never actually seized Geronimo, it wore him down to the point of surrender. Wood&#8217;s journal is a firsthand account of what men saw and felt on that dirty, brutal chase through desolate country where the temperature soared to 120 degrees. Unlike official military reports, Wood&#8217;s diary vividly describes the strains and weariness, the scant rations and long rides, the quarrels and casualties that soldiers suffered on the western frontier.<DIV>&nbsp;<DIV>Jack C. Lane&#8217;s annotation enriches Wood&#8217;s journal with sidelights on people, places, and events. His introduction tells how the 1886 campaign against Geronimo was the climax of the Indian wars in the West.</DIV>
