I have no clue as to why the link no longer functions, but PM your email address and I will send you a copy. That rule set is nearly four years old but there is supplemental information posted to the blog.
The first hour (4 turns) the Umayyad took advantage of the Alani misfortune and take the offensive.
Despite a few low pip scores the Alani brought the score even, 6 – 6 by turn 10.
The following turn the Umayyad were able to hold their momentum resulting in a narrow victory of 8 - 7.
The rule of thumb regarding the number of LH is possibly sound advice for tournament play, but refighting historical battles, I find the larger single commands demonstrate a huge improvement over the standard game of twelve elements.
