A courageous performance from the the newcomers saw them get the three points.
The game got off to a breathtaking start as St. Pauli went ahead as early as the sixth minute. Bastian Oczipka broke free on the left and crossed from near the corner flag for the overlapping Marius Ebbers, who made no mistake from inside the six-yard area, powering a header that hit the right post before crossing the goal line.
Despite being a goal down, Hannover were not in any hurry to fight back as the game's tempo rapidly dropped. Neither team managed to create anything of note until the 30th minute when Mohammed Abdellaoue put his header from the right side of the penalty area wide of the post.
In the closing minutes of the first half Ebbers could have completed his brace, had it not been for Karim Haggui, who made a wonderful sliding interception to prevent a Fin Bartels cross from reaching St. Pauli's No. 9 in the six-yard box.
This proved to be the final action of interest in the first 45 minutes as the two teams withdrew at half-time with St. Pauli nursing a slender lead.
The second half continued in the same pattern in which was played the first period with St. Pauli putting in an impressive defensive performance and Hannover struggling to break a resolute visiting defense.
The first real chance after half-time came as late as the 63rd minute when Ebbers tried to score from a tight angle near the left post, following a cross by Bartels from the right wing which everyone thought would go out for a goal kick, but instead hit the side netting from around three yards out.
In the following attack the hosts almost managed to grab an equalizer when Abdellaoue's header from just outside the six-yard box was impressively palmed away by Thomas Kessler.
Hannover's cause was not helped by Haggui who received a straight red card after taking down Matthias Lehmann near the penalty area semi-circle in the 80th minute, denying a great chance for St. Pauli on the break. Neither side managed to grab the attention in the remaining minutes as the game finished 1-0.
Hannover's next match is away to Bayern Munich on October 16, while the newcomers are set to host Nuernberg on the same day.
