The Great Northern War, which began in 1700, marked the end of the Pike and Shot era of warfare and ushered in the horse and musket era. The early stages of the era lacked the organization that we are used to in the Napoleonic era and still had some resemblance to massed bodies.

The Battle of Poltava was essentially a siege of several redoubts and forts that secured a key pass into Russia. The defensive Russians also had more forces than the Swedes, creating an interesting scenario. The Swedes tried to isolate each redoubt and take them one by one. The Russians were able to reinforce the redoubts. The Swedes were victorious in several instances.
