The 3/6th Battalion formed at Farringdon Rd in March 1915 some 1300 strong. Its early training was held in Regent's Park and Victoria Park, moving in August 1915 to Hurst Park Racecourse where the stands, outbuildings and stables were used as billets and the Royal Box became the Sergeants' Mess. As winter approached, the 3/6th moved to billets in Surbiton, training on Esher Commons. Then in January 1916 the battalion moved to Fovant on Salisbury Plain, where there was a large purpose-built training centre.
