On the 30th of March, about ten o'clock in the morning, the troops arrived at the foot of the eminence on which Chamula[XIII‑22] was situated. The ascent, at the only point where attack was possible, was impracticable for horsemen. Marin therefore ordered the cavalry to take up a position on the level ground below, and to protect his rear while the assault was being made.[XIII‑23] The infantry and allies then scaled the height and were soon in front of the fortifications, which they found to be of a formidable character. A palisade of strong cross-timbers let deep into the ground and firmly bound together was the first obstacle to their entrance, and behind it was a bulwark of stone and mud nearly twelve feet high and four feet in thickness, into which were inserted strong beams. This again was surmounted, along its whole length, by a wall of heavy boards six feet high, supported by strong crossbars on both sides, all firmly lashed together, while at intervals loop-holed turrets had been erected commanding the approach. At the strongest part of this bulwark was the single entrance, which was approached by a narrow flight of steps leading to the top. [Sidenote: HARD FIGHTING.] Though astonished at the strength of these ramparts, the Spaniards did not hesitate to assault them; but during the whole of the day all they could effect was the destruction of the outer stockade. Repeated attempts were made to mount the steps, but at each effort the assailants were driven back by the long heavy spears of the defenders. Incessant volleys of missiles were directed against them; their ranks suffered severely; and it soon became evident that some other plan of attack must be adopted.[XIII‑24] The only practicable one which suggested itself was to break open the wall with picks and crow-bars under cover of wooden sheds. Natives were therefore despatched for implements to the valley where the baggage and wounded had been sent under the protection of ten of the cavalry; and the besiegers now constructed several strong frames, each capable of holding twenty men.[XIII‑25] These were pushed up to the wall, and under cover of them the Spaniards began to break through it. The Indians poured on them burning pitch, scalding water, firebrands, and hot embers,[XIII‑26] and finally crushed them with heavy rocks, making it necessary to withdraw them for repairs. Then in mockery and contempt they threw golden ornaments[XIII‑27] at the retreating Spaniards, and with taunting words derided them. "Is it gold you want? We have abundance of it; why come ye not in and take it?"
