The casualties in the hard-fought battle of Ligny were very heavy.
The captures of the corps came to over 4,000 prisoners and 87 guns; the attacking strength of the Australians was less than 6,000 and the casualties were just over r,000 in all.
At the cost of only Boa casualties it had penetrated some 31 m.
On the night of the 23rd-24th, just as the assault was being renewed, Stessel delivered a fierce counter-attack against the lost positions, and the result of an all-night battle was that though the forts were not recaptured, the assault was repulsed with over 5000 casualties, and the Japanese in Pan-Lung were isolated.
In World War II, even more battles had a million casualties each.
