Afstan: The US Army in Arghandab: a tale of two battalions

Further to this post,

Command problems for US Army in Arghandab district

a very detailed account of the background--with much interesting tactical and operational detail--is given by Gulliver at Ink Spots (via BruceR's Update at Flit). The second battalion is part of the CF's Task Force Kandahar, scroll down to "U.S. Army units".

Before the second US Army battalion took up position Canadian troops briefly returned to part of Arghandab after the first US Army battalion, which never was under Canadian command, was deployed elsewhere in the district.
