Hitler thought it was a concept novel.
But wrong he was.
India knew Blitzkrieg long before Hitler.
In ancient dramas like Mahabharata,
And of course the older Ramayana,
The epics are replete with incidents,
Or rather determining acts of battle,
That determined the course of time,
Armies attacked the relaxing armies,
Changed the outcome of war.
So was the ancient Indian ideology.
