Geographical Features: Many battles were named after the geographical features near which they took place. For example, the Battle of Gettysburg was named after the town of Gettysburg, Pennsylvania, where it occurred, and the Battle of Antietam was named after the Antietam Creek, which ran near the battlefield.

For example, the Battle of Shiloh was named after Confederate General Albert Sidney Johnston, who was killed during the battle, and the Battle of Chancellorsville was named after Confederate General Robert E. Lee, who led the Confederate army to victory.
Events or Strategies: Other battles were named based on significant events or strategies that occurred during the fighting. For example, the Battle of the Bulge was named after the German offensive that created a bulge in the Allied lines during the winter of 1944-1945, and the Battle of the Coral Sea was named after the major naval battle that took place in the Coral Sea in May 1942.

It's worth noting that the naming of battles was not a standardized process during the Civil War, and different units and sources might refer to the same battle by different names. Additionally, some battles have multiple names due to different perspectives or historical contexts.
