Challenges: 1. Steal a carriage without entering the courtyard. 2. Don't let the royal carriage's condition drop below 50%.
Move to the south corner of the building and take down the guard on the roof with a knife headshot. Climb to his position and scan the area and roof. Don't enter the courtyard; instead, take out the guards on the balcony below (with knife headshots), followed by the guards on this roof. Check the courtyard; one of the carriages should be on the move soon. When this happens, quickly exit the area and follow the carriage. If nothing happens for some reason, use a smoke bomb next to the horse to scare it away. In any case, follow the carriage and hijack it. Sometimes there's a a second carriage outside, making it even easier to collect one. Once you've got a royal carriage, be careful when driving.
The rest of the mission is very straightforward. You must pick up three people so the Maharaja can speak to them. There will be some minor obstacles along the way, such as firefighter carriages, but it's very easy to dodge them.
