He simply gave the soldiers a salute, before heading out, knowing that finding him, hard at work, already on the field, would bolster morale FAR more than speeches, which they likely got quite often from the sergeants and officers. Though the quality would, no doubt, greatly vary between the various ranks. He was a sergeant, so his speeches were basically, 'up and at 'em, or else you answer to me,' types, so hardly inspiring.<br/><br/>He found the field easily enough, and its smaller size was actually a boon, as began magically creating the bulwark the soldiers would be behind from stone, carefully transmuting mud into stone, at least until he felt proficient with the spell, which didn't take long. The wall he made wasn't big, maybe three feet high, but easy enough to reinforce, and would provide a solid foundation for their own fortifications. That took most of the first day, and he recovered his energy and contemplated the field at the end of it, carefully breaking his four kegs of blasting powder into sixteen smaller ones. They would be scattered about the field, in created boulders about the size of a man, but he was planning to make several dozen of the man sized ones. After the first group of six exploded, the trolls would likely realize the entire field was mined, and charging would be next to impossible. Especially since he wasn't going to advertise which were the real ones, and which weren't.
