I've read both of these, and there are some problems with using Crook as the focus for discussions of the efforts against the Apache. For one, it tends to ignore the fact that there were a number of tribes in the region (Hualapai and Yavapai to name two) that drew on resources prior to 1871. Another issue is that Crook in most cases expanded on practices that were already in place before he arrived in Arizona. Both Thomas Devin and James Carleton before him had used small commands, mule trains, and local auxiliaries (Carleton more than Devin) in their operations. The difference is that both men (and other officers in the region under their commands) lacked the skilled PR machine the followed Crook.

That said, Greenberg's paper is especially balanced in its presentation of Crook and his operations. Well worth a read if you want a quick overview of operations during this period.
