"R.D. Dandekar, who subscribed to the Aryan migration model, proposed a fairly sober reconstruction of the Battle of the Ten Kings, but was more honest in admitting, “I must hasten to add that the Dåsaråjña has nowhere in the Vedic literature been described in a consistent and connected narrative. [...] I have collated the relevant material from the various versions of the Dåsaråjña, have tried to eliminate the inconsistencies and deficiencies in them as far as possible, and have reconstructed a plausible history mainly with the help of constructive imagination.” He was also not sure that the number “ten” should be taken literally; it “has to be understood as being only generally descriptive rather than definitive”."
