What befell the Russian army during the Azov campaign?

If we talk about the Azov campaign in 1695, then after 2 attempts to storm the Azov fortress, the siege was lifted. The first attempt was unsuccessful and led to the loss of personnel. The second attempt was more successful. The troops penetrated into Azov, but due to the lack of coordination in actions, they were forced to retreat.

The Azov campaign in 1696 was much more successful. A naval blockade of the fortress was arranged and artillery was largely involved. Azov gave up.

The government realized the importance of the navy and artillery. It was decided to create a regular navy.
