In April, Peter the Great managed to bring through a fleet of 250 ships to deliver guns and supplies, and to help perform a final assault on Swedish positions. After these Russian attacks, the Swedish garrison surrendered on 12 June 1710.

. It was therefore considered possible that Peter the Great himself would command forces at Vyborg, so that he would not have to reassign these experienced commanders and thus jeopardize the attacks on Riga.

Fortifications at Vyborg

In 1709, the main fort at Vyborg consisted of five frontal bastion

s named Holtz, Neuport, Klein-Platform, Wasserport and Eleonora, connected by a stone wall, in the eastern section of the town. The western part of the town, connected to the main section, had three bastions named Valport, Panzerlachs, and Evrop. To the west of the wall between Panzerlachs and Evrop, there was a ravelin

 and two caponiers, and to the west of the wall between Evrop and Eleonora was another ravelin. Both ravelins were, apparently, earthen, but inside the main eastern fort, all structures were stone. Most of the structures in the western part of the fort were wooden, with the exception of the stone guard tower, named the Petersburg tower. Separate from these fortifications, on the small central island east of the town (now the Zamochnyy Island), was Schloss (Castle) Vyborg, which stands to this day. The fort had 151 guns at its defense.

By this time, the fortifications had fallen into disrepair because the Swedish command did not pay much attention to these territories, and funds that were allotted for renovation were insignificant. In addition, the forts at Nöteborg and Nyenschantz were considered sufficient to provide defense for the region. In 1702, however, some repairs were completed under the supervision of Captain L. Stobecks.

According to Yuri Moshnik, a modern historian, the garrison at Vyborg in 1710 stood at 6000 men; other modern historians B. Adamovich and A. I. Dubravin put the number at 4000. Since 1702, the commander there had been Zacharias Animoff, who was old and in poor health. For that reason, in February of 1710, Colonel Magnus Stiernstråle

 officially replaced him; he had de facto headed the efforts to fortify the city.

Previous attempts

Russia had made a previous attempt to capture Vyborg; in October 1706, a siege corps was sent there under the command of Robert (Roman) Bruce. On 22 October, mortar

s were placed and the bombardment began, which continued for four days and caused five fires in the fort at Vyborg. After the bombardment, Russian forces retreated to Saint Petersburg after commanders realized that a siege could not be carried out without naval support and larger cannon. Also, autumn was not considered a suitable time for siege operations. The idea to reattempt a capture of Vyborg was first proposed by Peter the Great in 1708, but rejected by the military due to the recent Swedish offensive.

Russian attack

Peter's plan for the second siege of Vyborg involved a combination of land and sea forces, and the fort was to be taken by a prolonged siege. By February 1710, a specialized siege corps had been assembled on Kotlin Island

. This time, the Russian attack came in two stages. On 2 March 1710, General Apraksin received orders to attack Vyborg, and he planned to move out by 15 March. However, on 16 March, he was still on Kotlin Island, from where he wrote to Robert Bruce that he was departing on "the day of tomorrow". In fact, he only set out on 21 March, arriving with the cavalry on that same day at Vyborg; the infantry and cannon arrived the next day.

Russian forces arrive

When the siege corps arrived at Vyborg on the 22nd, they immediately occupied the settlement, forcing the Swedish defenders to withdraw to the fort. The Swedes had attempted to burn down the town itself to prevent it from falling into Russian hands, but failed to do so before they were driven into their fortifications. On that same day, as Apraksin reported to the czar:
"We neared the fort itself in approaches, which took a great effort, since at that time there was great cold, and in addition to that the situation around the fort is rocky, which caused significant upturn; however, despite the difficulty, the approaches have brought us to the sea strait, which is right under the city itself, at the distance of a musket's shot, with which bags full of fur were very helpful, where there were bare rocks. And for the other side ... to perform the approaches, Major-General Bergholtz was sent out with six regiments, which were also nearing the city with approaches."

These advances took place under Swedish artillery fire. From 21 March until 29 March (when, according to Aleksander Myshlayevsky

s were released by Swedish artillery. Also, the Swedes attempted a ground assault, but were driven back into the fort.

Number of artillery pieces

Estimates of the number of artillery pieces taken to Vyborg differ widely according to the various sources. In most sources, including Journal ... of Emperor Peter the Great from 1698 to the Treaty of Nystad, "Report on the capture of Vyborg", "The Life and Affairs of the Great Sovereign", and The Vyborg Fortress: Chronicles from 1710 to 1872, it is said that there were ten 12-pounder gun

. N. G. Ustryalov believed that there were ten 12-pounders and five mortars, M. M. Borodkin counted 24 cannon and four mortars, and M. V. Vasiliev 12 cannon and four mortars, although none of these historians give their sources for their figures. A letter from Fyodor Apraksin to Peter the Great dated 2 April 1710 stated that "the enemy has constructed three batteries against us; they shoot powerfully and accurately: one of our cannon, they have broken, another blew up from frequent firing; we have, remaining, 10 cannon in our batteries." (This was the only recorded time during the siege when Swedish artillery managed to disable Russian equipment.) Thus, Myshlaevsky concluded that there were originally 12 cannon brought to Vyborg, but only ten of them were used in the siege, as two of them were disabled. There were probably three mortars, although there are no primary sources to validate this.

In any case, there was not enough artillery, but new pieces could not be brought in. This was because it was very difficult to move them over land, and there was not enough ice to bring them over the sea.

Initial bombardment

It is not certain on what day the Russians began shelling the fort. Based on reports by Apraksin to Peter and on Peter the Great's Magazine, Russian artillery opened fire on 1 April. However, Apraksin reported to the czar that he "began bombarding Vyborg and the castle on 30 March, and on the first day 130 bombs were planted, and 90 on the second." Furthermore, Aleksander Myshlayevsky published a "List of how many shots were fired from mortars and cannon at Vyborg from 21 March to 9 April, and how many of them hit the city." There, it claims that shelling began on 29 March, when 150 mortar shots and 60 cannon shots were fired. It continues, saying that during the next three days only the mortars were used, firing 100 shots per day. In total, during the first period of the siege, the attackers fired 2,975 shots from mortars and 1,531 from cannon, and the Swedes fired 399 mortar shots and 7,464 cannon shots; thus the Swedish fire outweighed the Russian fire. On 5 April, Apraksin noted that "our cannon are doing little to help us, for they are rather small and light; when we begin firing, the opponent shoots one out of ten." However, the mortars inflicted great damage upon Vyborg and the fort, forcing citizens to find cover in cellars. Despite this, soldiers had to remain positioned on the mounds, and suffered heavy casualties.

Soon, Major-Generals Bruce and Bergholtz turned to Apraksin with a proposal to assault the fort, not waiting for "the production of an opening". Their reasoning was that they could end up losing more soldiers from injuries and disease than they would during an assault. Peter, having found out about this from a letter by Apraksin, decided it to be "very significant, but also very dangerous." In the end he left the decision up to General Apraksin who, not wanting to bear the responsibility for a failure, decided to wait for reinforcements to arrive by sea once the ice had opened up.

, where Captain Solovoy received them.

Peter did not wait for the cannon and, on 30 April, set out with his fleet to sea. He could not postpone his sailing due to a shortage of ammunition and provisions at Vyborg. Because the ice had not completely melted, the trip to Vyborg was very difficult. When the ice was particularly thick, crews had to resort to "hauling a small cannon onto the bowsprit

 and dropping it onto the ice" to break it. Many provision transport ships were driven off course by winds or ice, and they were barely rescued. When Peter's fleet finally arrived on 9 May, the Russian troops had only three days of provisions left.

Upon arriving at Vyborg, Peter immediately inspected Swedish fortifications and devised "Instructions on preparations for an assault on Vyborg". In it were plans for constructing two cannon batteries and three mortar batteries, with a total of 60 cannon and 18 mortars directed toward the Vyborg fort. It was also ordered that 140 light mortars be placed to knock enemy troops from walls during a final assault and to perform nighttime bombardments. Peter noted that that left 20 cannon, ten mortars and 50 light mortars in reserve, which could be used during a full barrage of the fort. He also proposed using fire ships from the sea, although they were never used.

Construction on the batteries mentioned in Peter's "Instructions" began on 17 May, and some of them were finished by 24 May. The Vyborg Fortress: Chronicles from 1710 to 1872 mentions that during the construction, a truce-bearer was sent out from the Vyborg fort with a request to Russian forces to allow passage for a courier

 to deliver letters to the Swedish general Georg Lübecker, but the request was denied. There are also records that show a Swedish fleet arriving at Vyborg and being beaten back by the Russians. However, other sources do not mention the truce-bearer or the naval battle; Fyodor Apraksin even wrote to the czar saying that he "could not imagine" how a Swedish fleet could be sent to Vyborg, although he did take precautions. During this time, Ivan Botsis

Final barrage and Swedish surrender

In a letter on 29 May, Fyodor Apraksin noted that work on the artillery batteries on his side of Vyborg were finished, and that there was still progress to be made toward completing the batteries on Bergholtz's side (although ten mortars were already in place), because of "great swamps and rocky [soil]". He asked Peter whether to wait for Bergholtz to finish building his batteries or proceed in the barrage without him; Apraksin himself was leaning toward the latter option, because he did not want to lose time and supplies, and because that side of the fortress was too heavily fortified for Bergholtz's guns. The czar agreed that there was no reason to wait, and ordered that the bombardment start as soon as possible. However, this led to another problem: it was impossible to quietly transport artillery over the rocky soil. There was also more daylight by that time of the year, and due to Vyborg's location in the northern latitudes, the sun only set around 9:00 pm. This meant that twilight

 lasted almost all night, and Swedish defensive fire could continue for longer, inflicting further casualties.

Nevertheless, the second barrage of the fort began on 1 June; by then, Bergholtz had 13 additional cannon at his disposal. The barrage lasted until 6 June, as a result of which "there was made a great breach, that two battalions were lined up on either side to take the city". During those six days, there were a total of 2,975 mortar shots and 1,539 from cannon. The Swedish fired 7,464 shots from cannon and 394 from mortars. Both the first and second barrages had a similar number of shots fired, but the second barrage was a lot more devastating to the Swedish. This was due to several factors; the shots fired during the second bombardment used higher-caliber

 ammunition and did greater damage per round, and the rate of fire was much more intense. The first bombardment took a month, whereas the second only took six days.

On 6 June, the decision was made to make a final assault on the fort. The next two days were spent in preparation, and those who would lead the "storm" were already chosen. However, on 9 June, the Swedish side sent out another truce-bearer, who said they were ready to surrender

 at Vyborg officially surrendered before any direct assault took place. The surrendered Swedish garrison numbered 3,880 men, including 156 officers and 3,274 soldiers of lower rank. Swedish losses were estimated at around 2,500.

Aftermath

In his letters announcing the capture of Vyborg, Peter the Great wrote that from now on the "final security of Saint Petersburg has been achieved." The czar said that Vyborg should become a "firm cushion" to the new capital. By capturing Vyborg, several important strategic goals were achieved.
