Balignant episode

Okay, I hope there are some people with a knowledge of The Song Of Roland
here. Footnotes in several translations state that the Balignant episode starts on line 2609. However, none of these have a footnote that points out the ending of the episode. Does anybody know the approximant line that ends the Balignant interpolation?

Baligany dies in Lais 263, which I think ends around 3665.

Thanks for the reply.
