As clan badges, both symbols were in common use among most of the Indian tribes. The turtle clan, says Heckewelder, was the governing family in any nation, and among the Delawares claimed an ascendency over the wolf and turkey families on account of its superior antiquity and relationship to "the great turtle, the Atlas of their mythology, who bore the great island--the earth--upon its back."
The hawk totem, which of course the Delawares might have applied to any people they chose, irrespective of its real emblem, occurred among the Hurons, and in both the Seneca and Cayuga tribes of the Iroquois confederacy; also among the Ojibways, Pottowatamies, Miamis, Abenakis, Sacs, and Foxes, and in many other tribes.
The account goes on to say that "the enemy fortified their large towns and erected fortifications, especially on large rivers and near lakes, where they were successively attacked and sometimes stormed by the allies. An engagement took place, in which hundreds fell, who were afterwards buried in holes or laid together in heaps and covered over with earth. No quarter was given, so that the Alligewi, at last, finding that their destruction was inevitable if they persisted in their obstinacy, abandoned the country to the conquerors and fled down the Mississippi River, from whence they never returned. The war which was carried on by this nation lasted many years, during which the Lenape lost a great number of their warriors, while the Mengwe would always hang back in the rear, leaving them to face the enemy."
In this description of a superior race of Indians, conquered after a most desperate resistance, and whose memory still survives in the great mountain chain to which they have given a name, we find a key to the often-spoken-of mystery of the mound-builders and their sudden disappearance.
The story of their long death-struggle and final overthrow by a horde of savage invaders, as here given in the formal style of Heckewelder, seems somewhat colored by his well-known partiality for the Delawares. It is confirmed, as we shall see, by the evidence of other Indian traditions and the study of their language, which seems to show that this people,--the Alligewi or mound-builders--fleeing down the Mississippi, were received and adopted by the Choctaws and Cherokees, themselves in comparatively recent times a mound-building people, and who thus have become in part their descendants.
