ABSTRACT
In author thesis of thirty-five years ago chapter four, The Earl of Warwick, 1456–60', was what the author called the fulcrum of argument regarding sea power, official understanding of its nature, and the deployment by government of that power. It was Richard Neville, Earl of Warwick at Calais and on the Narrow Seas who made the Yorkists into an opposition worth supporting: New Model Yorkism authors might want to call it, as after 1456 there was little life left in the Old Yorkist Cause. On 26 November 1457 Richard Neville, Earl of Warwick, indented with the king; the indenture was long and had been carefully considered: it followed the format of the indenture with the Sea-Keepers of 1454, who had included Warwick's father. Warwick's two sea battles of 1458 demonstrate this clearly. Both of necessity and of choice he saw that he could do much for himself, and the Cause, in the Channel.
