In the years after the pandemic subsided in many areas of the world, there were still small outbreaks, and pockets of cholera remained. In the period from 1823 to 1829, the first cholera outbreak remained outside of much of Europe. Its spread into Europe in the years after the initial outbreak started with the spread of the bacterium to the Russian empire yet again. Historians theorize that the spread back into Europe was largely to due to its movement in the Russian river system. This movement of the virus in the rivers of Russia allowed cholera to reach England by 1832, and the Americas shortly afterword. The bacterium also was theorized to have spread into England from British soldiers returning home after tours of duty in India, many of them serving in the Bombay Army which was stationed where the pandemic broke out. Special deputations from the west traveled to Russia to observe the Russian response and formulate a plan to deal with these pocketed outbreaks.  Reports from this committee of scientists were bleak, with a Dr. Rauch proclaiming that, "the cholera will not be cured by nature's powers alone without the help of art...". The conclusion of Dr. Rauch's findings was that no one standardized method was the key to controlling an outbreak. By 1835, these pockets of the bacterium claimed hundreds of thousands of lives. This timeline from 1826 to 1837 is widely described as the second cholera pandemic. One of the seven main cholera pandemics in history, extending into the modern day.
