Resting  at  Nottingham  he  issued  letters  of  array  to
the  lord-lieutenants  of  counties  charging  them  to
muster  all  trained  men  and  to  equip  them  well  in
readiness  thoroughly  to  defend  him  and  his  realm
from  the  traitorous  attacks  of  '  one  Henry  Tydder,
son  of  Edmund  Tydder,  son  of  Owen  Tydder,  who  of
his  insatiable  ambition  and  covetousness,  pretended
title  to  the  crown  of  England."

By  the  beginning  of  August  Henry  of  Richmond  had
landed  on  the  coast  of  Wales  and  had  sent  letters  and
issued  a  proclamation  asserting  his  claim.  Some  of
his  chief  supporters  were  Welsh,  and  to  them  he  wrote
in  terms  implying  that  there  could  be  no  question
as  to  the  Tightness  of  his  attempt  to  secure  the
throne  :  '  purposing  in  all  haste  possible  to  descend
into  our  realm  of  England,  not  only  for  the  adoption
of  the  crown,  unto  us  as  of  right  appertaining,  but
also  for  the  oppression  of  that  odious  tyrant,  Richard
late  Duke  of  Gloucester,  usurper  of  our  said  right.  .  ..
