Grimbsy Mariner, on his blog last week, threw me into a panic over the organisation of a Swedish battalion in the Great Northern War. In particular he had, like me, put his pikes in a block in the centre with grenadiers on the flanks. He had read that this was wrong, however, saying that: "Poltava, The Battle That Shook Europe" makes reference to pikes scattered through the battalion. However, Pat Condray in his booklet "Swedish & Russian Armies of the Great Northern War" (1990) is less clear. He talks about pikes being a third of the company strength and deployed either in the center of the battalion, the center of the company or across the width of the battalion."
After a lot of web trawling I cam across this which offers two alternative deployments:
I will happily stick to my pikes in the centre approach as a result, as the alternative smaller pike blocks would only work if you were using 6mm or 10mm figures I reckon.
