The spoil was great and the result decisive. For years afterwards the "Moors" cherished a wholesome dread of Krishna Raya and his valiant troops, and the Sultan, panic-stricken, never again during his enemy's lifetime ventured to attack the dominions of Vijayanagar. Krishna Deva, flushed with victory, returned at once to the attack of Raichur, and the fortress was after a short time captured.
Its fall was due in great measure to the assistance rendered by some Portuguese, headed by Christovao de Figueiredo, who with their arquebusses picked off the defenders from the walls, and thus enabled the besiegers to approach close to the lines of fortification and pull down the stones of which they were formed. Driven to desperation, and their governor being slain, the garrison surrendered.
Now as to the date of this battle.
I am bold enough to believe, and defend my belief, that when Nuniz fixed the day of the great fight as the new moon day of the month of May, A.D. 1522, he made a mistake in the year, and should have written "1520."
The chronicler states that Krishna Deva was prepared to give battle on a Friday, but was persuaded by his councillors to postpone his attack till the following day, Friday being unlucky. The battle accordingly took place on the Saturday, which was the new moon day.
Before proceeding to examine the month and day, let us consider the year A.D. of the battle.
Paes describes two grand festivals at the capital of which he was an eye-witness, and at which Christovao de Figueiredo was present. He fixes definitely the days on which these occurred. The first was the nine-days MAHANAVAMI festival, and the second was the festival of the New Year's Day. Paes states that on the occasion when he was present the MAHANAVAMI began on September 12 ("ESTAS FESTAS SE COMECAO A DOSE D魽S DE SETEBRO E DURAO NOVE DIAS"), and the latter began on October 12 ("ENTRAMDO O MES D OUTUBRO A OMZE DIAS AMDADOS D ELE ... NESTE DIU COMECAO O ANNO, E DIA D ANNO BOM ... COMECAO O ANNO NESTE MES COM A LUA NOVA, E ELLES NAO CONTAO O MES SE NAO DE LUA A LUA"). Previously to this, when writing about Raichur, Paes has described that place as a city "that formerly belonged to the king of Narsymga (I.E. Vijayanagar); there has been much war over it, and THIS KING took it from the Ydallcao" (Adil Shah). The chronicler, therefore, was present at these feasts on an occasion subsequent to the date of Krishna Deva's conquest of Raichur.
Now the MAHANAVAMI festival begins in these tracts on the 1st of the month of Asvina, and the New Year's Day in the time of Paes was evidently celebrated on the 1st of the month Karttika, as was often the case in former years both days being the days following the moment of new moon. In what year, then, during the reign of Krishna Deva Raya, did the 1st of Asvina and the 1st of Karttika fall respectively on September 12 and on October 12? I have worked these dates out for all the years of the reign, and I find that in no year except A.D. 1520 did this occur. In 1521 the MAHANAVAMI fell on September 2, and the New Year's Day on October 1; in 1522 the former fell on September 20, and the latter on October 20. This shows that Paes assisted at the festivals of A.D. 1520, and that therefore the battle and capture of Raichur must have taken place before the month of September in that year.
