The Indians got their footing into the match as time went by and took the lead in the seventh minute through Dilpreet, who pushed the ball in past Great Britain goalkeeper after being fed by Simranjeet Singh.
It was Simranjeet who created the chance after he stole the ball from a Great Britain defender just outside the latter's circle.
Two minutes from the first quarter, India custodian P R Sreejesh made fine reflex saves to deny Great Britain.
The Indians didn't let their rivals settle down and doubled their lead seconds into the second quarter through Gurjant.
It was Hardik who created the opportunity by intercepting a pass just outside the Great Britain 'D' and then sent the ball to an unmarked Gurjant, who kept a calm head to put the ball into the net through the legs of opposition goalkeeper Oliver Payne.
In the 35th minute, Gurjant had another chance to extend the lead but his reverse hit from a tight angle was easily saved by Payne.
Thereafter, it was all Great Britain as they pressed numbers in front in search of goals.
Leading by two goals, the Indians dropped back and tried to defend the lead but the move proved costly as minutes from the end of the third quarter Great Britain secured four back-to-back penalty corners the last of which was put into the back of the net by Ward.
With 15 more minutes remaining and just a goal behind, Great Britain went on the offensive in the final quarter, throwing numbers into their attacks as the Indians struggled to control the onslaught.
Great Britain succeeded in their efforts as they earned three more penalty corners in the match but th eredoubtable Sreejesh rose to the occasion and pulled off saves after saves to keep his side ahead.
India extended their lead against the run of play in the 57th minute when Hardik scored with a rebound from a counter-attack after his initial shot was saved by Great Britain goalkeeper Payne.
That goal sealed the tie in India's favour as down by two goals and with just three minutes remaining, Great Britain players' shoulders dropped down.
Once the hooter went off to declare the match's end, Indian players had tears of joy as they hugged and congratulated each other.
