Half a Banana is the wartime diary of Lieutenant-Colonel Peter Kemmis Betty, a young Gurkha officer captured by the Japanese after the fall of Singapore in 1942. Held in Changi POW camp, he and his childhood friend Alec Ogilvie spent over three years overseeing vegetable gardens that sustained thousands of Allied prisoners, fostering resilience and hope amid starvation, disease, brutality, and monotony. The diary offers a deeply human, uplifting depiction of camaraderie, morale, and resourcefulness, illustrating how ordinary acts—gardening, maintaining routines, and solidarity—helped preserve dignity. Published to mark the 80th anniversary of VJ Day, its proceeds support the Pahar Trust Nepal.
