Answer:
The correct order is:
I. Governor Martinez refused Moses Austin's plan
III. Baron de Bastrop helped Moses Austin
IV. Spanish government approved Moses Austin's plan
II. Moses Austin returned to Missouri
Explanation:
When in 1819 he initially presented the plan to the governor Martinez he was refused by him. Still, after that he presented his idea to Baron de Bastrop, who liked his idea of colonization. That is why he managed to present his case in front of the governor. This time governor agreed and Moses gain the approval of Spanish government. Still, he didn't live enough to fulfill his plan, as he died in Missouri in 1821.
