NEW YORK SEMI-WEEKLY TRIBUNE, Sept. 25, 1860  Perhaps the most significant report is headed, on the back page: "Capture of Walker - Full Particulars". William Walker was an American physician, lawyer, journalist, and mercenary. In the era of the expansion of the United States, driven by the doctrine of "manifest destiny", Walker organized unauthorized military expeditions into Mexico and Central America with the intention of establishing colonies. Ultimately, the 36 year-old Walker was sentenced to death, and executed by firing squad on September 12, 1860. 
Other items include a front page report from California via the Pony Express, and: "From The Pike's Peak Gold Region". Elsewhere: "The Calamity In Kansas" "Fugitive Slave Case In Ohio" and more.
Eight pages, good condition.
