Woodville movements between Sandwich and Towton

I wonder if anyone might help me in locating source materials
detailing the movements of the Woodvilles (Richard and Anthony) after
their capture at Sandwich in December 1459 and subsequent imprisonment
at Calais. They were, of course, free by the time of Towton. I
remember once seeing a reference placing them both at 2nd St. Albans,
although I am now unable to locate that reference, and I'm curious
about the timing and circumstances of their release.

Thanks,
Gary
