What type or pyrotechnic item is used for illuminating terrain for night time aerial reconnaissance photography?
Prior to the US Civil War Battle of Cold Harbor in June of 1864, General Grant had not ordered a reconnaissance of the terrain. A fundamental action when undertaking a major assault. Therefore when three of his corps began their assault against the enemy they knew nothing about the terrain nor the Confederate positions and their strength. The battle was a horrible defeat for the Union.
