SINGAPORE — Future generations must not forget the sacrifices made by Singapore’s pioneers, said the family of Lim Bo Seng, a World War II hero.

They were at a ceremony at Kranji War Cemetery yesterday morning to mark 70 years since his death at the hands of the Japanese military police during the Japanese Occupation in Malaya and Singapore.

The ceremony was organised by Changi Museum.

Lim Bo Seng was one of many operatives in Force 136 tasked to infiltrate and conduct sabotage missions in Japanese-occupied Malaya.

The agents were trained in India and sent to missions which were often dangerous, but conducted by ordinary civilians who were compelled by a greater cause.

His son, Dr Lim Whye Geok, who attended the ceremony yesterday, said he was only four years old when his father left Singapore to join Force 136. He said his memories of his father have been built up through stories shared by his eldest sister and from a diary Lim Bo Seng had left behind for his wife after his death.

Lim Bo Seng’s daughter, Ms Lim Oon Geok, said: “In his letter to my mother, he had written that when you start something, no matter what, you have to see it to its end. And he did say that when he bid goodbye to all of us, he never thought that it was eternal.”

As Singapore turns 50, his family hopes the legacy and sacrifices made by him and other pioneers will not be forgotten.

Mr Lim Teck Yin, Lim Bo Seng’s grandson, said: “For me, when I had the opportunity to read my grandfather’s diary, the full extent of the sense of sacrifice and the pain particularly of leaving behind my grandmother and the children remains very stark in my memory.

“For Singapore going forward, we always need to remember that we stand on foundations that our pioneers have set and that every generation has to build for the next generation.”

Lim Bo Seng died in a Perak prison in 1944. His remains were later buried at MacRitchie Reservoir in 1946.
