The South Saharan steppe and woodlands ecoregion is a narrow band running east and west between the hyper-arid Sahara and the Sahel savannas to the south. Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200 mm (3.9 to 7.9 in) but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses. This ecoregion covers 1,101,700 km2 (425,400 mi2) in Algeria, Chad, Mali, Mauritania, and Sudan.

Which directions does the South Saharan run?
Answer: east and west

For over a century, New Haven citizens had fought in the colonial militia alongside regular British forces, as in the French and Indian War. As the American Revolution approached, General David Wooster and other influential residents hoped that the conflict with the government in Britain could be resolved short of rebellion. On 23 April 1775, which is still celebrated in New Haven as Powder House Day, the Second Company, Governor's Foot Guard, of New Haven entered the struggle against the governing British parliament. Under Captain Benedict Arnold, they broke into the powder house to arm themselves and began a three-day march to Cambridge, Massachusetts. Other New Haven militia members were on hand to escort George Washington from his overnight stay in New Haven on his way to Cambridge. Contemporary reports, from both sides, remark on the New Haven volunteers' professional military bearing, including uniforms.

How long did the march from New Haven to Cambridge, Massachusetts take Arnold and his men?
Answer: a three-day march
