The Mexicans made the most of the lull in the fighting, and whilst the Spaniards gathered in their camp, discussing the unexpected turn of events, Roger and his friends perfected their arrangements for retirement, for it was clear to all that prolonged resistance could not be offered. And, indeed, they soon had cause to congratulate themselves on their caution; for Cortes was roused by the failure of his attack, and within an hour he sent his complete force against the wall, some seven hundred Spaniards attacking with unparalleled fury. Roger and his command resisted with determination, and held the wall till it was obvious that further delay would be disastrous. Then Teotlili put his fingers to his lips and sounded a shrill whistle.
"That is the signal," he said, "and the men with the lances are even now retiring by the aqueduct. We will give them a little while, and then the others can go."
"But we must beat the enemy back before they move!" exclaimed Roger. "For otherwise they would be in our ranks before we were clear. Let them collect here, and we will dash out at them with a hundred lances."
Again the prudence of their young English leader helped the Mexicans, and when the call came for a hundred of the lancemen to stay, a thousand eagerly offered their services. However, Teotlili soon picked out a chosen band, while the others retired swiftly, and without being seen. Then the crossbow-men were ordered to increase their fire, till the attackers were confused.
"Now we will charge," said Roger, placing himself at the head of the men. "Once we have met them, let every one turn and run as you give the signal."
Half an hour later the whole command was back in Mexico, very few men having been lost, while the Spaniards had had numbers killed or wounded, and their native allies had suffered heavily. Then for an hour the crossbow-men kept up a stinging fire, while the enemy destroyed the landward end of the aqueduct.
"It is a misfortune which cannot be helped," said Teotlili, as he watched the process of destruction, "and it would have been better for us had the people taken your advice, and sent all the women and children away to the hills. But the times are strange ones. We of Mexico have many enemies, and it is likely that our womenkind might fall amongst those who are unfriendly. Still, their presence here adds to the mouths to be filled, and to the numbers requiring water. For that we must rely upon the large storage tanks which we have constructed. And now, my lord, what arrangements shall be made with regard to the brigantines?"
They went in search of Peter Tamworth, while their look-outs posted on the summit of every temple sent them word of the movements of the enemy. And very soon they learned that the brigantines were afloat in the lake, and were to be expected very soon.
"Then, we will send out a fleet to meet them," said Roger, with decision. "I grant that our chances are not very great, but it happens that there is very little wind, and in a light breeze our small canoes can paddle faster than one of these Spanish vessels, while our new craft can sail with them, at least, if they cannot outstrip them. We will try what huge numbers and a fierce attack will do."
"And meanwhile I will communicate the news which has just reached me," said Teotlili. "Our scouts and spies have obtained full information of the movements of the enemy, and of their method of attack. He is a crafty man, this Malinché, and he is closing a huge net about us. Already he has marched his men completely round the lake, and now he has divided them into three divisions."
