In September 1914, the BEF was reinforced by the Indian Expeditionary Force A which eventually formed two corps each of two divisions, the Indian Cavalry Corps and the Indian Infantry Corps. Upon arrival in Marseilles on 30 September 1914, only six weeks after the declaration of war, they were moved to the Ypres Salient and took part in the Battle of La Bassée in October 1914. In March 1915, the 7th (Meerut) Division was chosen to lead the assault in the Battle of Neuve Chapelle. The Expeditionary Force was hampered by a lack of familiarity with new equipment, only being issued Lee–Enfield rifles on their arrival in France and they had almost no artillery, relying on support from their neighbouring corps when in the front line. They were not accustomed to the continental weather and were poorly equipped to resist the cold, leading to low morale which was further compounded by the reserve system, whereby reinforcements were drafted in from any regiment and had no affiliation to their new units. Officer casualties were even more of a handicap, as replacements were unfamiliar with the Indian Army and could not speak the language. The infantry divisions were finally withdrawn to Egypt in October 1915, when they were replaced by the new British divisions of Kitchener's Army.
