The trailer of Akshay Kumar's upcoming film Gold has impressed one and all.

Whoever has seen the trailer is raving about it. Hockey player Balbir Singh Sr. also liked the trailer so much so that he couldn't stop himself from penning down a heartfelt letter.

For the uninitiated, Balbir Singh Sr. is one of the most important players who participated in 1948 London Olympics and helped India win its first Gold medal in Hockey as an independent nation.

Here's what Balbir Singh Sr. wrote on his Facebook account:

THE GREATEST DAY IN THE HISTORY OF INDIAN SPORTS!

INDIA participated in 1948 London Olympics AS AN INDEPENDENT COUNTRY FOR THE VERY FIRST TIME!

On 12th of August, 1948 -Indian Hockey Team Played the Olympic Finals against Britain at Wembley Stadium, London & won!

-It was the FIRST EVER match in the Olympics between former Champions ( our former rulers) England & ( their "GULAMS" just a year before!) INDIA and that too, in their capital city of London!

The BBC calls India's victory over England - ONE OF THE MOST POLITICALLY SIGNIFICANT MOMENTS OF THE OLYMPICS"

Significantly- INDEPENDENT INDIA'S TRICOLOR FLUTTERED FOR THE FIRST TIME AT ANY INTERNATIONAL EVENT & OUR NATIONAL ANTHEM PLAYED FOR THE FIRST TIME IN OLYMPICS!

I was part of this Olympic Victory since the first two goals were scored by my stick within 15 minutes which pumped up the morale of Team India and resulted in Olympic Gold for INDIA!

As a 24-year-old - it was my debut appearance in Olympics! It was a great moment to be able to contribute towards the honor of Tiranga! I still remember OUR TIRANGA going up...it felt as if I am flying higher and higher along with the Flag & The National Anthem sounded so sweet to the ears! It was a great moment, cannot be explained in words - the actual feeling can only be experienced! In my heart, I remembered & finally understood my freedom fighter father's words who always talked about free India -our own National Flag and our National Anthem!

I am pleased that with the forthcoming Akshay starrer movie called 'GOLD ' is inspired by the gold medal winning 1948 Olympics INDIAN hockey team.

More importantly, & hopefully, the movie will familiarize our younger generations with golden Historic Facts & I will be able to re-live some special moments of my life!
