A new documentary released Wednesday commemorates a daring World War II operation to rescue Allied prisoners of war on South China's Hainan island, shedding light on a little-known chapter of history to mark the 80th anniversary of the victory in the Chinese People's War of Resistance Against Japanese Aggression and the World Anti-Fascist War.

The film, Unlocking Pigeon Mission, details the rescue carried out on Aug 27, 1945, 12 days after Japan's unconditional surrender. A nine-member Sino-American team parachuted into Basuo in today's Dongfang city to liberate over 200 Allied prisoners of war who had endured nearly three years of brutal captivity and forced labor. More than 500 prisoners, including members of Australia's Gull Force, were initially sent to the camp; fewer than half survived.

The documentary follows Australian researcher Brendan John Worrell as he revisits Hainan province to piece together the fragmented history. His investigation uncovered a story extending beyond a military operation, highlighting the courage and compassion of local Chinese civilians.

Through interviews with witnesses, including 100-year-old former laborer Zhang Renchang, the documentary shows how local Chinese workers and guerrilla fighters risked their lives to secretly provide food and aid to the prisoners - a critical lifeline during their captivity.

Ultimately, the documentary serves as a universal warning, portraying war as a devastating nightmare that brings profound suffering to all humanity. It underscores that peace, like air and sunshine, is precious and must be safeguarded. The film aims to deliver a timeless message: international solidarity and the collective pursuit of peace are powerful forces against evil, capable of transforming an island of captivity into a symbol of freedom and shared humanity.
