The title says Walmart beats Amazon in a battle. Then in the article it says:
"Flipkart’s board ultimately decided a deal with Walmart is more likely to win regulatory approval because Amazon is the No. 2 e-commerce operator in India behind Flipkart and its primary competitor. Amazon is out of the running unless Walmart hits unforeseen trouble."
It was a battle because Amazon went to the table to negotiate knowing they would not win. Their entire reason for entering the negotiations was to drive up the price for Walmart.
You don't have to win every battle to win the war.
I think it was a battle in the sense of "Amazon made Walmart pay a shitload and the Flipkart founders wanted the safest possible route to close because holy shit dat money"
"Flipkart’s board ultimately decided a deal with Walmart is more likely to win regulatory approval because Amazon is the No. 2 e-commerce operator in India behind Flipkart and its primary competitor. Amazon is out of the running unless Walmart hits unforeseen trouble."
Doesn't sound like a battle to me.
