When general Jacques Collyns returned to Europe on 15 September 1911 from his work as a state inspector in the Belgian Congo, Adipanga accompanied him and went to Brussels where he founded a family.

Several Congolese volunteers enrolled, including Paul Panda Farnana and Adipanga.

Under the lead of Louis-Napoléon Chaltin, Adipanga fought during the Siege of Namur, but was captured by the German Army, together with Farnana and Albert Kudjabo.

Wounded in action, he received eight Chevrons de front [fr] for his service during the war.
