If you look back at letters written by soldiers during the Civil War, the most recorded events were weather conditions.

From around 1310 to 1850, there was what scholars dubbed the Little Ice Age. Even though there was a general cooling pattern, there were also dramatic weather fluctuations. The Civil War would have likely felt the effects of the weather period.

The Battle of Fredericksburg occurred between December 11–15, 1862, throughout Fredericksburg, Virginia and surrounding areas.

The battle was between the Union Army of the Potomac and the Confederate Army of Northern Virginia.

The Confederate Army of Northern Virginia had about 78,000 men and the Union Army of the Potomac had around 120,000.

Because of these uneven numbers, Gen. Robert E. Lee, the Confederate Army leader, used a high-ground artillery strategy rather than trench work.

On December 15, there was such a thick fog that cavalry commander J. E. B. Stuart suggested that the Confederates launch a surprise attack under its cover. However, Gen. Lee did not give the go-ahead.
