The
First World War began in August 1914, a war that pitted the British Empire,
France and their Allies against
Germany and its allies. During the conflict, the Regiment saw service in
Africa and the
Middle East. The 101st raised a 2nd Battalion in 1917 which saw service in
Egypt; it was disbanded in 1921. The Regiment took part in operations in
German East Africa from the beginning of the campaign there in November 1914. There, the British encountered a formidable opponent in the form of
Paul Erich von Lettow-Vorbeck. The 101st took part in the initial landings and the
Battle of Tanga. This was a German victory, that saw the British and Indian forces, including the 101st, sustain significant casualties that compelled them to retreat back to their ships. 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, indeed, successfully captured. Some of von Lettow-Vorbeck's forces had remained to snipe at the Indian forces; these
snipers proved to be quite a deadly nuisance that required intense patrolling to remove the threat. For the ''Regiment's'' involvement in the campaign it was awarded the Theatre Honour "East Africa 1914–16". The 101st later saw service in the Middle East in the
Palestine theatre – this theatre was the second largest, in terms of troop numbers, after the
Western Front. Their opposition was the
Ottoman Empire that controlled
Palestine, and was an ally of Germany. The Regiment took part in the attempts to capture the important port of
Gaza and by the end of December 1917 the Allies were in control of much of Palestine, including the symbolic capture of
Jerusalem. In July 1918 the
Regiment took part in the Ghurabeh raid that saw intense fighting and over 100 Ottomans taken prisoner. The Regiment later took part in the
Megiddo Offensive – the World War I equivalent of the German
Blitzkrieg during
World War II – and took part in the attempts to capture
Nablus. The Ottomans signed an
Armistice with the Allies on 30 October. The First World War finally ended on 11 November 1918 with the signing of the Armistice between the Allies and Germany. ==Post-War==
