What did Danglars accomplish after Dantes was put in prison?

From the text:

Why, he left Marseilles, and was taken, on the recommendation of M. Morrel, who did not know his crime, as cashier into a Spanish bank. During the war with Spain he was employed in the commissariat of the French army, and made a fortune; then with that money he speculated in the funds, and trebled or quadrupled his capital; and, having first married his banker’s daughter, who left him a widower, he has married a second time, a widow, a Madame de Nargonne, daughter of M. de Servieux, the king’s chamberlain, who is in high favor at court. He is a millionaire, and they have made him a baron, and now he is the Baron Danglars, with a fine residence in the Rue du Mont-Blanc, with ten horses in his stables, six footmen in his antechamber, and I know not how many millions in his strongbox.”
