The Landing Craft Personnel Medium answered problems encountered on shingle beaches and supported commando work. Dieppe appears here as confirmation of lessons already visible in Ceylon and earlier operations, especially the danger of trying to seize a defended port. The planning matched neither the opposition nor the weight of the force committed, and Louis Mountbatten's direction of Combined Operations receives direct criticism. A light force could raid quickly, while a formation carrying heavy equipment was conducting an assault and needed much more firepower. The Landing Craft Support Medium grew because small assault hulls were useful landing craft but unstable gun platforms. Dieppe finally persuaded sceptics that previously reported problems were operational realities.

Dieppe, raiding limits, and stable gun platforms
Dieppe confirmed that a heavy assault was not a light raid and that effective landing-craft gun platforms needed size and stability.
