Volume 22 contains works and articles Marx and Engels wrote between July 1870 and October 1871. Most of the works, articles, statements and letters sent by Marx and Engels to newspapers, are directly connected with their guidance of the International. The First and Second Addresses of the General Council of the International Working Men’s Association on the Franco-Prussian War included in this volume, were official documents of the International and outlined a comprehensive solution of both national and international problems facing the proletariat at the time. Much space is accorded to Engels’ articles on the Franco-Prussian War of 1870-71 published in the Pall Mall Gazette in London. Written in the form of separate military surveys, they are closely interconnected and form a single series. For this reason these articles are published here as a separate work under a general title “Notes on the War”, a title given to most of the articles in the series by the author himself.
