The statement is true. The Indian sepoys, who were native soldiers serving in the British Indian Army during the British rule in India, were indeed unhappy about their pay, allowances, and conditions of service. Several factors contributed to their dissatisfaction, ultimately leading to the outbreak of the Indian Rebellion of 1857, also known as the Sepoy Mutiny.

1. Low Pay:
- The sepoys received significantly lower salaries compared to their British counterparts in the army.
- This pay disparity was a major source of discontent among the Indian sepoys, who felt undervalued for their service.

2. Discrimination in Allowances:
- The Indian sepoys were not provided with the same allowances and privileges as the British soldiers.
- They were not granted the same amount of financial benefits, such as pension and gratuity, which were given to the British soldiers.
- This discrimination further fueled their dissatisfaction and feelings of injustice.

- They were required to serve in various parts of India as well as in foreign territories, such as Afghanistan and Burma.
- The sepoys had to face challenging circumstances, such as extreme weather conditions, lack of proper accommodation, and inadequate medical facilities.

4. Cultural and Religious Grievances:
- The Indian sepoys also had cultural and religious grievances.
- There were rumors that the cartridges of the new Enfield rifles were greased with animal fat, which offended both Hindu and Muslim sepoys.
- The use of animal fat violated their religious beliefs and cultural practices, leading to widespread resentment.

5. Lack of Promotions:
- The sepoys faced limited opportunities for promotion within the ranks.
- The British officers held the higher positions, while the Indian soldiers were rarely promoted to higher ranks.
- This lack of upward mobility added to their frustration and discontent.

In conclusion, the Indian sepoys were indeed unhappy about their pay, allowances, and conditions of service.
