In 1782, William Hornby assumed the office of Governor of Bombay, and initiated the Hornby Vellard engineering project of uniting the seven islands into a single landmass. The purpose of this project was to block the Worli creek and prevent the low-lying areas of Bombay from being flooded at high tide. However, the project was rejected by the British East India Company in 1783. In 1784, the Hornby Vellard project was completed and soon reclamations at Worli and Mahalaxmi followed. The history of journalism in Bombay commenced with publication of the Bombay Herald in 1789 and the Bombay Courier in 1790. In 1795, the Maratha army defeated the Nizam of Hyderabad.
