From African Kaiser: General Paul von Lettow-Vorbeck and the Great War in Africa, 1914-1918, by Robert Gaudi (Caliber, 2017), Kindle Loc. 365-394:
Today, a bronze historical marker in Belgium memorializes the first British shot of World War One and the first death in battle involving British troops. According to this marker, the opening round of uncountable millions was fired by Corporal Ernest Thomas of C Squadron, 4th Royal Irish Dragoons on August 22, 1914, in a cavalry action near the town of Casteau, Belgium. The first combatant killed, a German uhlan (mounted infantryman), is credited to Captain Charles B. Hornby in that same action. Captain Hornby pierced the unfortunate uhlan’s heart by saber thrust—an ironically old-fashioned death (on horseback, with a sword) in what was to become a decidedly modern war (mechanized, faceless), its human toll exceeding 14,000,000. But the markers’ assertions do not stand historical scrutiny; their authors disregard earlier campaigns in far-off Africa.
The first British shot of the war actually occurred on August 5, fired off by Regimental Sergeant Major Alhaji Grunshi, a black African soldier serving with British Imperial forces a few miles north of Lomé, in German Togoland. The first recorded British death in battle, one Lieutenant G. M. Thompson of the Gold Coast Regiment, took place sometime over the night of August 21–22, also in Togoland: Lieutenant Thompson, given command of a company of Senegalese Tirailleurs, fought it out with German askaris in a confused action in the thick bush on the banks of the river Chra. His comrades found him in the morning, lying dead and covered with insects in the midst of his slaughtered command. They buried them that way; the Senegalese arranged around Lieutenant Thompson’s grave like a loyal pack of hounds around the tomb of a Paleolithic chief.
After less than a year of war, the German Overseas Empire—one of the main catalysts for the war in the first place—seemed nearly at an end.
In China, on the other side of the globe, the small German garrison holding the Kiao-Chow Concession found itself besieged by a Japanese Army 23,000 strong, supported by a small contingent of the 2nd Battalion of South Wales Borderers. The Concession—a 400-square-mile territory centered in the fortified port city of Tsingtao on the Yellow Sea—had been ceded to Germany in 1897 as compensation for the murder of two German Catholic priests by anti-Christian Chinese mobs. Tsingtao’s commandant, Kapitän zur See Meyer-Waldeck, held out against the siege behind the city’s thick walls for two months, under continual bombardment from land and sea as Japanese Infantry assault trenches pushed relentlessly forward. Realizing the pointlessness of further struggle against the combined might of the Japanese Army and Navy, Meyer-Waldeck surrendered his garrison of 3,000 German marines and sundry volunteers at last on November 16, 1914. It came as a surprise to him that the Japanese and the British were fighting together against Germany—they had signed a secret mutual defense treaty in 1902, only now bearing fruit.
Meanwhile, Australian, New Zealand, and Japanese forces easily captured German possessions in the South Pacific. These included the Bismarck Archipelago, the Caroline Islands, the Marshall Islands, the Marianas, Palau, New Caledonia, and Samoa—where the Kaiser’s barefoot native soldiers sported fetching red sarongs beneath their formal German military tunics—and Kaiser-Wilhelmsland, now the northeastern part of Papua New Guinea. Here one intrepid German officer, a certain Hauptmann Herman Detzner, who had been off exploring the unknown interior with a contingent of native police, refused to surrender and remained on the loose in the wilderness for the duration of the war. He turned himself in to the occupying Australians on January 5, 1919, wearing his carefully preserved and outdated Imperial German uniform—a kind of German Rip van Winkle who had been asleep in the jungle while the world changed irrevocably around him. By July 1915, of Germany’s prewar colonial possessions, only German East Africa remained.
