The subject of generals killed in action post-1900 holds a bizarre and somewhat morbid interest for me. It’s a period where personal presence on the battlefield was theoretically less important thanks to the use of the telephone and later radio. It’s also a period where fighting formations became exponentially more powerful.
Not surprisingly, the World War II Eastern Front takes the cake. Although there were exceptions, American general officer casualties were surprisingly low-they were comparable in both World War II and Vietnam despite the lower casualties of the latter war.
For a later period hypothetical WWIII/high intensity peer war, I have a tentative list of dead generals that mainly includes air/missile strikes (including a corps commander and some of his high-end staff taken out by a hit on their badly sited HQ). Besides those and maybe a few shot-down ones, there’s an example I made of the commander of an airborne division killed by a tank raid on a forward helicopter base he’s visiting.
Earlier, I have considerably higher casualties among general officers. This is because there’s often more divisions and because worse C3 means the generals have to be at the front more often.
