I took the view that since one aeroplane had just aquaplaned off the runway, there could be a strong chance that another could do the same.
I totally agree with your concern. The tower was totally in the wrong for clearing a landing while you guys were busy in the overun. But I assume your's was a peacetime event. The Red Horse crews were working in the middle of a war. Big difference. These guys accepted it as part of their job description to take such risks during war. To me, it's unacceptable to impose such risks on others in peacetime, especially without even informing you of the risk before hand. Good for you that you got pi$$ed and good for you that you chewed them out. They deserved it.
