[6] Pope Honorius III (1216–1227) received a number of petitions regarding new Baltic crusades, mainly concerning Prussia and Livonia but also a report from the Swedish Archbishop concerning difficulties with their mission in Finland.

[11] According to the chronicle, on receiving the news of the advancing Swedish, Norwegian, Finnish and Tavastian fleets, the 20-year-old Prince Alexander Yaroslavich of Novgorod quickly moved his small army and local men to face the enemy before they had reached Lake Ladoga.

But still protected the merciful, man-loving God us and sheltered us from the foreign people, and the word came to Novgorod that Swedes were sailing to Ladoga; but prince Alexander did not hesitate at all, but went against them with Novgorodians and people of Ladoga and overcame them with the help of Saint Sophia and through prayers of our lady, the Mother of God and Virgin Mary, 15 July, in the memory of Kirik and Ulita, on Sunday, (the same day that) the 630 holy fathers[12] held a meeting in Chalcedon; and there was a great gathering of the Swedes; and their leader called Spiridon[13] was killed there; but some claimed that even the bishop was slain;[14] and a great number of them fell; and when they had loaded two ships with the bodies of high-born men, they let them sail to the sea; but the others, that were unnumbered, they cast to a pit, that they buried, and many others were wounded; and that same night they fled, without waiting for the Monday light, with shame.

Of Novgorodians there fell: Konstantin Lugotinitch, Gyuryata Pinyashchinich, Namest, Drochilo Nezdylov son of the tanner, but including the people of Ladoga 20 men or less, God knows.

[17] After the death of King John in 1222, Sweden was in a de facto state of civil war until 1248 when Birger Jarl managed to seize power in the kingdom.

Mostly free to act without interference from the king, folkungs would have been able to raise an army of their own, get volunteers from Norway and even assistance from Thomas, the independent Bishop of Finland, who needed to constantly worry about attacks from the east.

However, some recent research has fundamentally questioned the importance of the battle, seeing it as an ordinary border skirmish that was exaggerated for political purposes, thus also explaining its absence from Swedish and other western sources.

[25] It has also been suggested that the suspicious information on Norwegians', Finns' and Tavastians' participation was made up in the 14th century, the time of writing of the First Novgorod Chronicle, when Sweden was in control of Norway, Finland and Tavastia.

The Swedish attack on the Neva River in July 1240 was one of a long series of hostile encounters over these issues, not, as is sometimes asserted, a full-scale campaign timed to take advantage of the Russians' adversity and aimed at conquering the entire Novgorodian realm.
