Problem: Further to the west, the Suez Canal was defended from Ottoman attacks in 1915 and 1916; in August, a German and Ottoman force was defeated at the Battle of Romani by the ANZAC Mounted Division and the 52nd Infantry Division. Following this victory, an Egyptian Expeditionary Force advanced across the Sinai Peninsula, pushing Ottoman forces back in the Battle of Magdhaba in December and the Battle of Rafa on the border between the Egyptian Sinai and Ottoman Palestine in January 1917. Russian armies generally had success in the Caucasus. Enver Pasha, supreme commander of the Ottoman armed forces, was ambitious and dreamed of re-conquering central Asia and areas that had been lost to Russia previously. He was, however, a poor commander. He launched an offensive against the Russians in the Caucasus in December 1914 with 100,000 troops, insisting on a frontal attack against mountainous Russian positions in winter. He lost 86% of his force at the Battle of Sarikamish.

Problem: Coming off their road win over the Lions, the Giants went home for a Week 12 intraconference duel with the Minnesota Vikings. In the first quarter, New York trailed early as Vikings QB Tarvaris Jackson completed a 60-yard TD pass to WR Sidney Rice. The Giants responded with RB Reuben Droughns getting a 1-yard TD run. Minnesota retook the lead with safety Darren Sharper returning an interception 20 yards for a touchdown. In the second quarter, Vikings' RB Chester Taylor got an 8-yard TD run, along with kicker Ryan Longwell making a 46-yard field goal. In the third quarter, Giants' kicker Lawrence Tynes made a 48-yard field goal, and Minnesota's Longwell made a 26-yard field goal. In the fourth quarter, the Vikings' safety Dwight Smith returned an interception 93 yards for a touchdown, along with LB Chad Greenway returning an interception 37 yards for a touchdown. New York's QB Eli Manning completed a 6-yard TD pass to WR Plaxico Burress to complete the scoring. Eli Manning was intercepted four times (with three of his interceptions being returned for touchdowns). He became the third NFL QB since 1970 to have three interceptions get returned for touchdowns. His performance was all the more embarrassing as the Vikings had the league's worst pass defense in 2007 (albeit with the league's strongest run defense), and were playing in this game without starting corner Antoine Winfield.

Problem: Between 1519 and 1523 there was a succession of heavy battles and smaller skirmishes, in the course of which many towns and villages were devastated. After futile sieges of the defences of Calenberg and Hildesheim by troops from Hildesheim or Brunswick as well as numerous trails of devastation and plundering by both sides against the civilian population, the two sides finally met on 28 June 1519 at the Battle of Soltau . The Hildesheim army scored an emphatic victory against the Brunswick-Welf troops, killing some 3,500 men and capturing one of their leaders, Eric of Calenberg, as well as many of the nobles. This signalled the end of the opening phase of the war. However, an appeal to the newly elected emperor, Charles V, who had a good relationship with Wolfenbuttel, saw the situation entirely reversed at a political level. The ruling imposed by Charles V provided for the surrender of all conquered territory and release of all the prisoners, and thus ruled very much against the Hildesheim side. Because it was ignored by the bishop and his allies, the emperor's decision was followed in 1522 by the imposition of an imperial ban, the execution of which was assigned to the princes of Wolfenbuttel and Calenberg. Whilst Henry of Luneburg had already gone into exile in France in 1520 having transferred the reins of power to his sons and in doing so keeping the Principality of Luneburg out of the subsequent conflict, there were renewed military clashes between the Hildesheim prince-bishop and his opponents that were not finally resolved until the so-called 'field peace' of 15 October 1521. Hildesheim had won militarily, but lost politically.
