 However, due to an 1882 statute limiting the number of available naval commissions, there were not enough vacancies in the service to retain all of the Academy's graduates.Jackson's poor grades placed him near the bottom of his graduating class, so he was to be cashiered from the Navy upon completing his sea duty.While awaiting his discharge, Jackson was serving aboard "Trenton" in Samoa when it was wrecked by the 1889 Apia cyclone on March 16, 1889.
