Finally, a new alliance started to be formed in 1939. The Kasprzycki-Gamelin Convention was signed May 19, 1939 in Paris. It was named after Polish Minister of War Affairs General Tadeusz Kasprzycki and Commander of the French Army Maurice Gamelin. The military convention was army-to-army, not state-to-state, and was not in force legally, as it was dependent on signing and ratification of the political convention. It obliged both armies to provide help to each other in case of a war with Germany. In May, Gamelin promised a "bold relief offensive" within three weeks of a German attack.
