Vallejo then invited the filibusters' leaders into his home to negotiate terms. Two other Californio officers and Leese joined the negotiations. The insurgents waiting outside sent elected "captains" John Grigsby and William Ide inside to speed the proceedings. The effect of Vallejo's hospitality in the form of wine and brandy for the negotiators and someone else's barrel of "aguardiente" for those outside is debatable. However, when the agreement was presented to those outside they refused to endorse it. Rather than releasing the Mexican officers under parole they insisted they be held as hostages. John Grigsby refused to remain as leader of the group, stating he had been deceived by Frémont. William Ide gave an impassioned speech urging the rebels to stay in Sonoma and start a new republic. Referring to the stolen horses Ide ended his oration with "Choose ye this day what you will be! We are robbers, or we "must" be conquerors!"
