Britain provided 10,000 troops, of which a large part were Indian troops, made out of units of Baluchis, Sikhs, Gurkhas, Rajputs and Punjabis. Germany had gained a presence in China after the Juye Incident in which two German missionaries were murdered in November 1897. The concession in Kiaochow with the port of Tsingtao, was used as a naval base for the East Asia Squadron and a trading port. The German concession was governed and garrisoned by the Imperial German Navy. At the outbreak of the Boxer Rebellion in June 1900, the garrison of the concession was composed of the "III. Seebataillon" with 1,126 men, a marine/naval artillery battery, about 800 men of a "Kommando" Detachment and sailors from the East Asian Squadron. With the increasing threat of the Boxers, a small armed group from the "III. Seebatallion" was sent to Peking and Tientsin to protect German interests there while the majority of the remaining forces stayed behind to prevent attacks against Tsingtao. The siege of the foreign legations in Peking soon convinced Germany and the other European powers that more forces were needed to be sent to China to reinforce allied forces. The first troops dispatched from Germany were the Marine-Expeditionskorps which consisted of the "I." and "II. Seebatallions". They were soon followed by the Ostasiatisches Expeditionskorps (East Asian Expeditionary Corps), which was a force of about 15,000 of mostly volunteers from the regular Army under the command of Gen Alfred Count von Waldersee. It comprised initially four and later six two-battalion infantry regiments and a Jäger company, single regiments of cavalry and field artillery and various support and logistics units. On arrival in China it incorporated the Marine-Expeditionskorps that had preceded it to China by a few weeks. However, the majority of the German forces dispatched arrived too late to take part in any of the major actions; the first elements of the Corps arrived at Taku on September 21 after the legations had been relieved. As a result, most of the Corps were mainly employed for garrison duties, though they did fight a number of smaller engagements against pockets of remaining Boxers. The Corps was later disbanded and recalled to Germany early in 1901. Three battalions of marines, the II/9th, and the I and II/11th RIMa which were stationed in French Indochina were sent to China.
