2018 marks the start of the celebrations of the 250th anniversary of Cook's Endeavour voyage (1768-1771). Never have Cook's journals and charts been subjected to such unbiased, forensic examination. The doubts, puzzles and queries raised by J.C. Beaglehole, Cook's renowned editor and biographer, are answered. Cook's discoveries had to remain secret until Britain could afford to send an occupation force to fortify the place and keep out the French hence the publication of Cook's censored journal and charts. Controversial, detailed, contentious and compelling.
