American Military History This is a chapter of American Military History , which was written by the Center of Military History , a branch of the United States Army . Congregational Christian and Evangelical and Reformed Church leaders already had begun private conversations about union when German Evangelical Church pastor , Martin Niemoeller was incarcerated in Nazi Germany for preaching the Christian gospel from his prominent Berlin pulpit . Recently , the total ruin of the Square was threatened by an ingenious proposal of Mr. Moses to push a four-lane highway through it in order to open up a clear passage to the lower part of the city and , not too incidentally , to give the people living in the group of tall , expensive apartments just south of the Square — the group called Washington Square Village — a Fifth Avenue address , which Mr. Moses , in one of his Pooh-Bah roles , had promised the owners . Finally , in the interactive Java applet , you can explore the properties of sections of convex polyhedra and find the maximum area sections and the sectional areas of arbitrary convex polyhedra .
