the 19th Century for its involvement in the war, "Burma 1885–87". 20th century In 1901 the Regiment deployed to the British territory of Aden (now part of the Yemen), also having its name changed to the 1st Grenadier Bombay Infantry. In 1903 the Regiment was renumbered to become the 101st Grenadiers. Elements of the Regiment saw service during operations in 1902–05 to quell an uprising by Dervishes, led by their sultan Diiriye Guure. During operations in Somaliland, Captain George Murray Rolland won the Victoria Cross (VC) for his actions at Daratoleh on 22 April 1903. The operations against the 'Mad Mullah' did not conclude until 1905 with the signing of a peace agreement—the Mullah gained some territory in Italian Somaliland. The Mullah reneged on this agreement when he resumed hostilities against the British in 1907, and would continue to do so until 1920. First World War The First World War began in August 1914, a war that pitted the British Empire, France and their Allies against Germany and its allies.

The 101st had however shown stubborn resistance when other units broke. In January 1915, a company of the 101st took part in the Battle of Jassin that saw both sides sustain heavy casualties which compelled von Lettow-Vorbeck to avoid pitched battles with the British forces. Due to this defeat, the British garrison in Jassin surrendered, after no relief force had arrived, with nearly 300 British and Indians troops taken prisoner, including the company of the 101st, but were subsequently released on parole with the pledge that they would have no further participation in the war. One company of the Regiment acted with the 5th Light Infantry in another attempt to capture Tanga in July 1916. The port—which had, for the most part, been abandoned—was,
