This is good. A little short for my taste, but good rhyme scheme. However, I don't think the commanders of any major war are careless, and often neither impatient or secretive. Many of the men knew what they were going into, on the secretive side. As for careless, no army commander can be careless. I think the reason orders were given with such haste was that if the commanders stopped to think about what they were doing, the lives they were taking, it would overwhelm them. They had made it rational in their heads, but it was fragile, and if they stopped to think, the horror of it all would catch up to them. And no one can deal with that. not careless, they couldn't escape caring, but they tried so hard. So hard.
