Waiting on the abatis to send my final kudos. But for those building such an entrenchment, the entrenchment here would be very adaptable to the Siege at Fort William Henry.
Fort William Henry (and France's Fort Carillon) could only accomodate about 400-500 soldiers. Any remaining soldiers would have to be housed outside the fort. Of about 2,200 troops under Monro at Fort William Henry, about 1,700 were positioned outside the fort protected by an wooden entrenchment that I would imagine to be very similar to Mike's entrenchment. There were a few cannon --- at least two 12 brass pounders and some brass 6 pounders positioned as part of the entrenchment with a large concentration of tents behind. Apparently, Monro spent the vast majority of his time during the battle at the entrenchment camp, not inside the fort.
From Edward Dodge's Relief is Greatly Wanted. "The garrison in the fort consisted of Captain Ormsby of the 35th as well as Lt. Good and Ensign Witherington of the 35th, 60 british regulars, 150 sailors and carpenters and during the day augmented with provincials to bring the garrison up to 400. Colonel Monro was outside the fort. This was 3 August."
It is my understanding the fort's cannon were manned by the sailors. I assume that most of the women and children would also be inside the fort. The vast majority of the 35th regiment was outside the fort with Monro.
There were a few indians at the Battle of Ticonderoga on the French side --- I think about 14 or 15. Admittedly, these Indians were probably with the French Marines or French colonials on the flanks, but I see no real problem with adding a favorite indian figure or two to any scene - maybe a figure from WIM-02, WIM-03 and/or WIM-04.
