HELP with mission 1 PLEASE

im 1 hour into this game. in the very first mission in the city of brahma or whatever where you need to sink two corsair ships. i found the istani oil, walkthroughs all say take oil to catapult then pull lever.

I get the oil, where do i put it? is there button im mission? I carry it to the cartapult, the bowl of the catapult is in the top position so i cant reach it to load in the oil, and the lever does nothing. Im very frustrated already lol so if anyone has any info thanks in advance
