Letters written by Adelaide de Montgolfier to Louise Swanton Belloc while the latter was in exile in England during the Franco-Prussian War. The letters describe the progress of the war and the deprivations caused by the Siege of Paris, also the state of affairs at the house at La Celle St Cloud, attempts to put things there into safekeeping etc. The first letters in the series predate the departure of Bessie and Louis Belloc for England with their children Marie and Hilaire. People mentioned regularly include Bessie and Louis; Catherine and Raphael (with whom Adelaide de Montgolfier lived during this period); Lily Ballot [née Belloc, formerly Millet], who also remained in France during this period because her son René was fighting; and Jacques [Redelsperger?].
