Vortigern was powerfully struck, as Hengist had anticipated, with her grace and beauty.

Learning that she was Hengist's daughter, he demanded her hand.

Hengist at first declined, but, after sufficiently stimulating the monarch's eagerness by his pretended opposition, he yielded, and the king became the general's son-in-law.

This is the story which some of the old chroniclers tell.
Modern historians are divided in respect to believing it.

Some think it is fact, others fable.
At all events, the power of Hengist and Horsa gradually increased, as years passed on, until the Britons began to be alarmed at their growing strength and multiplying numbers, and to fear lest these new friends should prove, in the end, more formidable than the terrible enemies whom they had come to expel.
