<p><b>Ouvrage Hackenberg</b>, one of the largest of the <a href="/pages/w/108358585859728">Maginot Line</a> fortifications, is part of the <a href="/pages/w/101155346635217">Fortified Sector of Boulay</a>. It is situated twenty kilometers east of <a href="/pages/w/108196772535362">Thionville</a>, in the <a href="http://en.wikipedia.org/wiki/Moselle_" class="wikipedia">Moselle <i>département</i></a>, near the village of <a href="/pages/w/110083299017331">Veckring</a>, on the <a href="/pages/w/391740860971738">Hackenberg</a> . It is located between <i>gros ouvrage</i> <a href="/pages/w/138290039533043">Billig</a> and <i>petit ouvrage</i> <a href="/pages/w/111093895607901">Coucou</a>, facing Germany. The fort occupies the wooded Hackenberg ridge. Before <a href="/pages/w/109429592416229">World War II</a> it was considered a showpiece of French fortification technology, and was visited by British <a href="/pages/w/114333785249475">King George VI</a>. In 1940 Hackenberg was never directly attacked, providing covering fire to neighboring positions and harassing nearby German forces. Its garrison was one of the last French units to surrender after the June 1940 armistice. In 1944, under German occupation, it was in action against American forces advancing along the Maginot Line. It resisted for three days before artillery bombardment from the rear forced the Germans to evacuate. Following World War II it became part of a strongpoint meant to delay a potential advance by Soviet forces into northeastern France. Hackenberg has been preserved and operates as a museum.</p>
