Lionel Wigrams' Letter on Lessons of the Sicilian Campaign, 16 October, 1943.

Stumbling on this piece sometime last year, I rather imprudently dismissed it as an historical eccentricity. Wilf drew my attention back to it not long ago, and I realized just how careless I had been in ignoring it. This ties well into Wilf's own articles "Patrol-Based Infantry Doctrine" and "Organising Infantry". For that matter, Wilf's own article on Lionel Wigram was just published last month in British Army Review.

In short, without giving away the specific contents of Wigram's letter, the organization and TTP's that Wigram proposed for Infantry Sub-Units and Minor-Units were (and to a certain extent still are) radical and eye-opening. It's reasonably short in length, but may lead to a fair bit of contemplation.
