Glancing through the 196 numbers of the Bulletin international des Sociétés de la Croix-Rouge certain major themes stand out significantly. Some of these were already described in its first issue of October 1869, then can be met with again throughout the years until this last number of October 1918 devoted almost entirely to wartime activities in 28 belligerent or neutral countries and to interventions on behalf of victims. The account which follows, however incomplete it may be, will at all events describe the successes, hopes and preoccupations of a decisive period in the history of our movement.
