Hi Clay,
Absolutely pikes were used by the Swedes and Russians in the GNW. There is some controversy about how much the Russians actually used pikes on the battlefield. As you say, just because they were officially issued pikes, does that mean that they were dragged along to battle?
Interestingly enough, it seems that few pikes were evident in the Russian army before 1700, as the Russians noticed that Western Europe had abandoned the pike pretty much by then. However, after fighting the Swedes, and seeing how effective the Swedes were with the pike, Russia reintroduced and started using the pike once more.
In the primary sources, pikes were listed as being issued to Russian units, and more importantly also were listed in material losses after battles, which strongly implies that they were actually used in battles post 1700. The ratio of pike to shot was quite low, well under the "traditional" 1:3 pike to shot ratio. Also, not all regiments seemed to have been issued pikes, so probably there were no regulations or universal standards about pikes. There isn't a lot of source material about pikes.
In 1723, Peter the Great ordered all of his pikemen to rearm with muskets and bayonets for a war against the Turks. I found that quite interesting that against an army with a high proportion of horse, that pikes were dispensed with. I had heard an argument that because Russians often faced more mobile opponents, pikes were more important. Apparently not, according to the Czar!
(This information is from Boris Megorsky's work, which seems the most exhaustive. Konstam states each infantry regiment was issued pike; Hoglund merely mentions pikes were used, but the extent is unknown).
In Maurice terms, I have about half of my regiments with pike. In those, I have four pike figures for 16 casting units, which of course makes no difference for Maurice, but I just like the ratio.
I'm honestly not sure how the pike rules will work in Maurice, as it seems almost an afterthought, but I suspect it will work well enough for me, and definitely give a different "feel" to a GNW army, as opposed to a SYW army.
I have heard the argument that some pikes were at Blenheim, but it is my understanding that that particular historical viewpoint is somewhat controversial in academic circles. I raised a French army for that conflict, so I didn't delve into that research too much.
Thanks for the link Steamingdave2. Very interesting discussion. From what I read, the Streltsy did not have pikes, except to carry pennants, so I'm a bit dubious about the accepted "Russians used pikes until 1720" blanket statement.
