In mid-August 1914 British mounted units moved into northern Kamerun from Nigeria to discover that the Germans under Captain Ernst von Raben had set up a fortified position on and around Mora mountain (Moraberg). When the Germans drove off their initial attacks, the British, joined by French arriving from Chad, set up a siege. Despite several more Allied assault attempts, the Germans held out until February 1916, by which time the fall of the rest of Kamerun convinced von Raben to surrender with his 155 remaining men.in wikipedia
By early September 1914 the German advance had reached the eastern outskirts of Paris, prompting the British Expeditionary Force (BEF) to consider evacuating France. They were persuaded otherwise by Joseph Simon Gallieni, the military governor of Paris, who launched a counter-offensive by six French armies and the BEF along the Marne River. The Allied attacks brought the Germans to a halt, then forced them back north 65 km to the Aisne. The threat to Paris had been ended, at the cost of some 250 thousand casualties on each side.in wikipedia

Learning that a British cruiser-HMS Pegasus-had arrived in Zanzibar for repairs, the German cruiser SMS Königsberg sailed from the Rufiji Delta into Zanzibar harbor. When Pegasus came within range, Königsberg opened fire; surprised, immobile, and outranged, the British ship was unable to mount an effective response and had to be abandoned after 40 minutes. With the destruction of Pegasus, Königsberg returned to the Rufiji Delta, bombarding the picket ship HMS Helmuth as it left Zanzibar harbor.in wikipedia
