In page Harold Godwinson:

"

According to Snorri Sturluson, before the battle a single man rode up alone to Harald Hardrada and Tostig. He gave no name, but spoke to Tostig, offering the return of his earldom if he would turn against Hardrada. Tostig asked what his brother Harold would be willing to give Hardrada for his trouble. The rider replied "Seven feet of English ground, as he is taller than other men." Then he rode back to the Saxon host. Hardrada was impressed by the rider's boldness, and asked Tostig who he was. Tostig replied that the rider was Harold Godwinson himself.[3] According to Henry of Huntingdon, Harold said "Six feet of ground or as much more as he needs, as he is taller than most men."
