All trading is halted on the Toronto Stock Exchange as three disc drives fail and computers crash. Scientists trace the failure to microchip interference from a geomagnetic storm caused by a massive solar flare, even larger than the one that took down Quebec’s power grid months earlier.
A geomagnetic storm is a temporary disturbance of the Earth’s magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth’s magnetic field. The increase in the solar wind pressure initially compresses the magnetosphere. The solar wind’s magnetic field interacts with the Earth’s magnetic field and transfers an increased energy into the magnetosphere.

Recognizing that his enemy is massing forces he can't take on, and fearing for his family, General William Hull surrenders Fort Detroit to the British. The action will result in a death penalty, but Hull's sentence will be pardoned due to his previous Revolutionary War heroism.
The Siege of Detroit, also known as the Surrender of Detroit, or the Battle of Fort Detroit, was an early engagement in the Anglo-American War of 1812. A British force under Major General Isaac Brock with Native American allies under the Shawnee leader, Tecumseh, used bluff and deception to intimidate the American Brigadier General William Hull into surrendering the fort and town of Detroit, Michigan, and a dispirited army which nevertheless outnumbered the victorious British and Native Americans.
