What did Czechoslovakia’s alliance with France require during the Sudeten crisis?

During the Sudeten crisis, Czechoslovakia relied on its 1924 treaty of alliance with France, which was intended to provide military assistance in the event of aggression. However, as the crisis escalated in 1938, the French government—anxious to avoid a military confrontation with Germany—began to distance itself from these obligations.12

In April 1938, legal interpretations published in France suggested that the treaty did not strictly mandate that France go to war to save Czechoslovakia. Ultimately, rather than honoring the alliance to defend Czechoslovak sovereignty, France joined Great Britain in pressuring the Czechoslovak government to cede the Sudetenland to Germany. By the time of the Munich Agreement, France had abandoned its commitments, leaving Czechoslovakia with the choice of resisting Germany alone or submitting to the mandated territorial annexations. This betrayal was famously lamented by the French ambassador, who noted that France had deserted its only faithful allies.123
