Hendon produced a performance of character but went down at high-flying Poole Town by the odd-goal in seven on Saturday afternoon.
Two goals from Tony Lee gave the Dolphins a 2-goal advantage inside 10 minutes, only for the deficit to be wiped out before half-time thanks to strikes from Dave Diedhiou and Joe White.
Lee completed his hat-trick to restore Poole's lead before sub Will Fletcher made it 4-2. Diedhiou set up a grandstand finish with his second goal of the afternoon with five minutes remaining. Despite ten minutes of stoppage time at the end of the second half, Hendon were unable to make their pressure count and the home side held on for three valuable points.
