Until the 1840s there had been a widespread belief amongst the Bengal sepoys in the "Iqbal" or continued good fortune of the East India Company. However much of this sense of the invincibility of the British was lost in the First Anglo-Afghan War where poor political judgment and inept British leadership led to the massacre of Elphinstone's army (which included three Bengal regiments) while retreating from Kabul. When the mood of the sepoys turned against their masters, they remembered Kabul and that the British were not invincible.
