Abstract: This anonymous strategic memorandum weighs objections to continuing the Mariana reduction against arguments for maintaining and strengthening it. It analyzes the islands’ value as a Pacific stopover, possible foreign occupation, risks to the Manila-Acapulco galleon route and the Philippines, Cavite’s strategic role, costs of ships and garrisons, potential ports and sailing routes, salvage of cannon and valuables from wrecked galleons, and the religious and geopolitical importance of a Spanish presence in the Marianas.
