Nuclear war in the 18th century

From 1780 to 1816, a nuclear war took place on Earth. In total,
about 800 megatons of bombs were dropped on the planet. This
is precisely what Russian researchers Nosovsky and Fomenko
assert in New Chronology. This is a summary of the facts of a
popular theory in Russia.
1) In the European part of Russia, from 1780 to 1816, strange
funnels appeared, filled with water, ranging in size from 100 m
to several kilometers. There are a lot of such objects. For example,
Dead Lake 20 km from the city of Penza. The lake is absolutely
round, 450 m in diameter. Such reservoirs have a water level much
higher than in neighboring rivers. Which indicates their recent
origin. For example, Devil's Lake, Shaitan Lake, Hell's Lake,
and so on.
2) It all started with the "Great Hurricane" in 1780, also known
as "Black Day". More than 27.5 thousand people in the Lesser
Antilles of the Caribbean became victims of the hurricane that
raged from 10 to 16 October 1780. In addition to the strong wind,
a decrease in the transparency of the earth's atmosphere was
observed as a result of nuclear explosions. Ashes rose into the
atmosphere and closed the sun.
3) Strangely, throughout the entire territory of Russia
(and this is 1/6 of the land), there are no forests over 200 years
old. Although in the medieval chronicles forests are mentioned
thousands of years old! For example, like sequoias in California.
Researchers believe the trees were destroyed by atomic fire. As
an example, the royal decree of the 19th century on the planting
of new forests on the central Russian plain is cited. Their number
was restored only by the middle of the 19th century by massive
planting in squares forms.
4) In ancient Russian cities, the first floors of houses built before
the 19th century simultaneously found themselves underground
at the same level. For example, in the city of St. Petersburg.
5) There are no 18th century cemeteries in Russia. There are only
early, medieval burials of the barrow type, or burials of the middle
of the 19th century. The cemeteries of the 18th century have not
survived. It is surprising that during the construction of the metro
in Russian cities, bones from this period were and are being found
in mines and under layers of soil.
6) For 36 years of this global war from 1780 to 1816, the huge
empire "Great Tartary" disappeared from the map of the world
(Encyclopedia Britannica, Vol. III, Edinburgh, 1771, p. 887, La
Geographie Universelle contenant Les Descriptions, les Cartes,
et le Blason des principaux Pais du Monde). The territory of this
empire was larger than the territory of modern Russia!
7) By the end of the war in 1812, the Little Ice Age began. The
summers of 1814, 1815, 1816 were cold and snowy. Because of
what the townspeople left Russian and European cities. People
thought that the end of the world was coming. Researchers believe
this is a consequence of a nuclear winter.
Who fought against the "Great Tartary" is not clear. But it is known
that after the destruction of this gigantic empire, Russia began to
seize its empty territories. The colonialists often found huge
abandoned and ruined cities. By the way, they marked on all
medieval maps as important! For example, the trading cities of
Grustina, Mangazeya, and so on. In general, the strange and
incomprehensible instant collapse of the huge empire "Great Tartary"
is directly related to the period of the Little Ice Age and nuclear
war.
