A new fleet was built, a new army was raised and on 31 October 1831, under Ibrahim Pasha, the Egyptian invasion of Syria started the First Turko-Egyptian War. The Egyptians overran most of Syria with ease. The strongest and only really significant resistance was put up at the port city of Acre. The Egyptian force eventually captured the city after a six-month siege. Unrest on the Egyptian home front increased during the course of the siege. Ali was forced to squeeze Egypt more and more to support his campaign, and his people resented the increased burden.
