These new volunteers served as a "new face, untainted by defeat and accusations of defeatism…to breathe life back into the campaigns and restore hope at home." Other changes enacted by the British immediately following the Black Week disaster were the mobilization of two more divisions, the calling up of the army reserves, raising a force of mounted infantry for better mobility, and most importantly by sending volunteers from home overseas which added more than one hundred thousand additional troops by the end of the war.
