While the Spaniards were enjoying here a few days of repose the chief of the district, Nutibara by name, quietly assembled an army of two thousand men, thinking to crush this presumptuous little band, for no tidings had yet reached him of the dread prowess of the strangers. A stubborn conflict ensued, terminated only by the death of Quinunchú, brother of Nutibara, who fell by the hand of César. Santiago on his white horse again appeared in behalf of his followers, and to him was ascribed the glory of the carnage that followed. The conquerors soon ascertained that the country for many leagues around was rising in arms against them, and having now secured treasure to the value of forty thousand ducats they returned by forced marches to San Sebastian.[II‑12] News of César's expedition was soon carried to Cartagena, whence in December 1537 the licentiate Juan de Badillo set forth to explore further the region south of the gulf of Urabá. A force of three hundred and fifty men was collected, with five hundred and twelve horses, a number of Indians and negroes, and ample stores of provisions and munitions of war. Francisco César was second in command, and the treasurer Saavedra one of the captains. Starting from the port of Santa María near the mouth of the Atrato they arrived, with no adventure worthy of note, at the valley of Los Pitos[II‑13] where was a fort defended by a large force of natives. Saavedra, leading an attack on this stronghold at the head of sixty men, was beaten back, and César, coming to his support about nightfall, posted his men in readiness to renew the assault at daybreak. The defenders, perceiving their design, determined to anticipate them, and fell on the Spaniards unawares, but after some sharp fighting were repulsed. Badillo then continued his march through the Guaca Valley, arriving at the domains of the chief Quinachi. It was here that César, on his first expedition, had unearthed treasure to the value of thirty thousand castellanos, and hence one reason for selecting this route. In June the expedition arrived at the valley of Norí,[II‑14] with ranks somewhat thinned by famine and by ceaseless encounters with the natives. Meeting with a friendly cacique they questioned him as to the whereabouts of the great treasure of Dabaiba. He replied: "There is no treasure, for they have no need of any; but when they want gold to purchase food or redeem a captive, they pick it up in dry weather from under the rocks in the river-beds." Exploring parties were sent in all directions, but with little success. They could not scale the steep sierra or cross the treacherous marshes, and they were constantly harassed by bands of Indians. Acosta relates that one detachment sent out toward the mountains in a westerly direction passed underneath a village, built amidst the overhanging boughs of forest-trees, whence the natives plied them with arrows, rocks, hot water, and lighted fagots.
