Babbage was very thorough, and spent a lot of time making sure that his information was correct. He carried a lot of equipment, as well as four and half tonnes of food, enough to last 18 months in the desert. Among his supplies he had 20 kilograms of chocolate and 5000 litres of water. He also took a flock of 150 sheep, which limited the speed the group could move. The government became frustrated with Babbage's slow progress, they wanted to know about possible farm lands and valuable minerals as soon as possible. Eventually Babbage was removed from the job and replaced by Major Peter Warburton.
