Curzon - the last of a dying breed
We already know that Curzon lacks close, emotional relationships because of his interactions with his wife and the men around him. So why does Forester include the presence of Curzon's unborn son in the novel, other than to further reveal the man's stoic nature upon the death of his child? I think that the child is an indicator that Curzon is among the last of a dying breed of men. After the war, there will be no use for men like Curzon since men like him are purported to be the cause of the war - or at least the reason for the war being fought the way that it was.
He is obsessively patriotic and his character is rooted in traditional methods of war. Curzon immediately imagines his child to be the same way and thinks to himself that "his son would be one of a military family now, General Curzon's eldest boy, and after him there would be a long unbroken succession of military Curzons" (138). The world definitely did not need more little Curzons running around to cause even more chaos. The premature death of the unborn baby, and the recommendation that Emily should not attempt to conceive another child again, can be seen as a sign that there is no room for more Curzons. Perhaps it is a message of hope for a war-ravaged country when Forester writes, "There would never be a Herbert Winter Grevan Curzon now. He was the last of his line" (202).
