Between the poop and forecastle (as was then the fashion) the upper-deck beams were left open and unplanked, with the exception of a narrow gangway on either side; and off that fatal ledge the boarders, thrust on by those behind, fell headlong between the beams to the main-deck below, to be slaughtered helpless in that pit of destruction, by the double fire from the bulkheads fore and aft; while the few who kept their footing on the gangway, after vain attempts to force the stockades on poop and forecastle, leaped overboard again amid a shower of shot and arrows.
