Hannibal Brooks

A British prisoner of war assigned to care for Lucy, the elephant. Resourceful and determined, he emerges as the de facto leader of the escape, balancing duty with compassion for those around him. He confronts moral dilemmas, including a deadly confrontation in which Kurt is killed, and presses onward toward Switzerland with tenacity.

A hostile German soldier whose aggressive behavior creates immediate danger for the group. His threatening stance toward Lucy escalates tensions and culminates in his death at Brooks' hands during a critical moment.

A friendly German soldier who becomes a reluctant ally, aiding Brooks and Lucy along the escape path. He shares in the risks of the journey, hoping for safety before being captured; he ultimately sacrifices himself as the Nazis close in.

A female cook who travels with the group, initially sharing in the escape plan. After capture, her loyalties shift, and she makes a final, selfless effort to warn others before she is fatally shot.

An American escapee who has formed a partisan resistance to fight the Germans. He provides leadership and protection as the group nears the Swiss border, continuing to wage conflict against their pursuers.

An SS officer in pursuit of the group who proposes a ruse to bluff their way through to Switzerland. His changing stance, rhetoric of defection, and ultimate betrayal add a dangerous layer to the escape drama.

The elephant entrusted to Brooks at the Munich Zoo, central to the escape narrative. Lucy's health and safety drive much of the plot, including medical care when she develops mumps and the emotional appeal for crossing to Switzerland.
