India were bowled out for a record low score of 36 as they were comfortably beaten by eight wickets by Australia in the first Test in Adelaide.
Not a single India player reached double figures in their second innings as Josh Hazlewood took five wickets for eight runs and Pat Cummins added four for 21.
India's innings ended when Mohammad Shami retired hurt after taking a blow on the arm from Cummins, still six runs short of their previous lowest Test score of 42, which came against England in 1974.
It left Australia chasing 90 to win, with Joe Burns making 51 as they reached the target in 21 overs to wrap up victory inside three days.
"It's very hard to find words to express how everyone's feeling in the change room," said India captain Virat Kohli, afterwards.
"When you work hard for two days, you play some good cricket to get yourself in a good position, and then literally in an hour you put yourself in a position where it's impossible to win."
"To get 100 ahead with wickets in hand would have been a good position to be in. But it's something that needs to be reflected on and learn from and we need to put in better performances going forward."
Kohli topscored for India in the first innings with a patient 74 but managed only four in the second, falling to a reckless shot.
The 32-year-old felt the Indian batsmen should have played with the same positive mindset they had showed during their first innings total of 244.
"They bowled similar areas in the first innings as well, but probably our mindset and intent was to get runs, even if it's ones and twos," Kohli said.
"To be honest, there were some good balls, but I don't think the ball did something drastic in the morning.
"It was just the mindset that put us into positions where the ball took edges and it was pretty evident in the way we went about things, just losing one (wicket) after the other."
India's meagre total was the lowest by any Test side since New Zealand set the all-time low of 26 against England in 1955 and the seventh lowest ever.
Ireland scored 38 in their second innings against the English in Lord's last year, which is now the eight lowest total.
