Synthesized answer
The name "Capua" is connected to a skull through a chain of associations. The narrator immediately linked "Capua" to "_caput mortuum_." This association was further reinforced by the fact that the narrator had often compared Veronica's head to a skull [1].
Additionally, an indirect connection is made through General Haynau, the "hyena of Brescia." From Haynau, a stream of thought leads to the "grave-digging animal with the hoarse voice," which corresponds to the thought of a monument to the dead, and subsequently to the skull [2]. The Hungarian word "_kapzoi_" (greed after money) also furnished a determinant for the displacement related to "Capua" [1].

she treated the children of the family was insufferable to me. Now I knew the significance of the substitutive thoughts. “To Capua I immediately associated _caput mortuum_. I had often compared Veronica’s head to a skull. The Hungarian word _kapzoi_ (greed after money) surely furnished a determinant for the displacement. Naturally I also found those more direct associations which connected Capua and Verona as geographical ideas and as Italian words of the same rhythm. “The same held true for Brescia; here, too, I found concealed side-tracks of associations of ideas. “My antipathy at that…
this country, as well as in North Italy, is that of General Haynau, who is briefly referred to as the hyena of Brescia. From the hated tyrant Haynau one stream of thought leads over Brescia to the city of Verona, and the other over the idea of the _grave-digging animal with the hoarse voice_ (which corresponds to the thought of a monument to the dead), to the skull, and to the disagreeable organ of Veronica, which was so cruelly insulted in my unconscious mind. Veronica in her time ruled as tyrannically as did the Austrian General after the Hungarian and Italian struggles for liberty.…

d lead to the reproduction of the lost name is, as it were, displaced, and thus brings one to an incorrect substitute. Now it is my assumption that the displacement is not left to psychic arbitrariness, but that it follows lawful and rational paths. In other words, I assume that the substitutive name (or names) stands in direct relation to the lost name, and I hope, if I succeed in demonstrating this connection, to throw light on the origin of the forgetting of names. In the example which I selected for analysis in 1898 I vainly strove to recall the name of the master who made the…
e miracle of St. Januarius into a clever allusion to the courses of the woman.” “It was surely without my knowledge. And do you really believe that my inability to reproduce the word ‘_aliquis_’ was due to this anxious expectation?” “That appears to me absolutely certain. Don’t you recall dividing it into _a-liquis_ and the associations: _reliques_, _liquidation_, _fluid_? Shall I also add to this connection the fact that St. Simon, to whom you got by way of the _reliques_, was sacrificed as a child?” “Please stop. I hope you do not take these thoughts--if I really entertained…
