Those who were at the scene after the incident told a slightly different story (apologies to his living relatives, if this narrative is wrong). The recruit, a tall gangly nerd just completed HSC before being drafted was originally from 5 SIR in Taman Jurong. He was one of the many excess recruits that 5 SIR had, and since the next door camp, I think 1st Artillery Battalion needed more recruits, he was transferred. Unfortunately the unit he was sent to, was already in the midst of grenade training which had not started in 5 SIR. Soon after the transfer, he went along with his platoon for live grenade lessons. The procedure as many knows was that after being given the grenade he was suppose to pull the pin and shout "Grenade" and then throw it over the bunker shelter. Then count the seconds 1 - 4 before getting into prone position to escape any shrapnels.
He pulled the pin and stood petrified, trembling and did not throw the grenade as instructed. 2Lt Tay shouted for him to throw but he was frozen, whereby 2nd Lt Tay decided to take the grenade by transferring it into his hand but still ensuring the grenade lever that held the detonating pin was intact. Holding the grenade behind him, he began to scold the recruit without realising that somehow, in the process of transferring, the lever had already released the detonating pin. The grenade exploded in his hand, damaging half his body at the rear and of course his hand was blown apart. The recruit escape serious injury and was almost unscathed as 2Lt Tay's body took the brunt and shielded him from the blast and shrapnels.
"“Rethinking the Who, What and When: Why not Singaporean Military Heroes?” Ho Shu Huang
Many Singaporeans recognise Major-General (MG) Lim Bo Seng’s name, but far fewer know who Second Lieutenant (2LT) Tay Siow Kai is. Second World War hero MG Lim has a memorial dedicated in his memory at Singapore’s Esplanade, and has been described as “Singapore’s best known war hero”. Yet, it was only recently, following a remarkably similar incident, that the heroism of National Serviceman 2LT Tay displayed while shielding a recruit from an exploding grenade during a training accident, resulting in his death, attracted renewed attention. The question at hand should not be whose contributions were more heroic but rather, how uncritical the appropriation of MG Lim as a war hero in the Singaporean national narrative has hitherto been. MG Lim was not Singaporean and considered himself an overseas Chinese nationalist patriot, trained by the British, and posthumously commissioned a Major-General by the Kuomingtang (KMT). 2LT Tay, on the other hand, was a true-blue Singapore citizen, trained by its own military, serving a country he would have undoubtedly, and immediately, called home. Why then is 2LT Tay absent from Singapore’s national narrative, yet MG Lim loom so large? This paper makes two main arguments. First, MG Lim’s appropriation as a Singapore war hero is unnatural. That title in fact is instructive – MG Lim can at best be a Singapore war hero, never a Singaporean one. The historical components of the person, event and period must be enlarged by paying attention to the stories of the ordinary, what some have referred to as the “underside” of history, so that more appropriate “military heroes” may emerge. Second, there will be a need for new military heroes from below. As younger generations become increasingly wary of the existing Singapore Story, new chapters of the national narrative have to be written about a comparatively less tumultuous present. The fixation on the larger- than-life personality and the historically grand event may be detrimental to nation-building in the long- term."
