Hello Josquin,
i respect your opinion, and my previous statement of hoping not to be revanchistic etc. is still in effect

However my idea of public international law does not match yours
I am aware that the finding of H.E. gun cotton and bigger artillery resources in the wreck would certainly be something else than the already known small arms ammunition, however the existence of H.E. cargo in those crates mentioned is not really proven yet.
Anyway in my opinion this would only be a marginal difference, because any ship carrying anything to support the Entente and entering British waters was prone to be a target for Germany. As mentioned before neutrality was often abused even by coal freighters, and it was common knowledge in the german Navy.
" ... clearly, it was wrong to transport war material on a
civilian passenger ship, and clearly it was wrong to lie at the time about the Lusitania 's status as a passenger ship exclusively. Unfortunately, as many
have observed over the centuries, it is far easier to get men to fight for
an idea rather than for real estate or the claims of a ruling elite. Hence,
we have propaganda ... "
So true. It seems the Lusitania was intentionally led by the admiralty on a path along the assumed position of the U-boat that then sunk her - the position was known due to the british code break early in the war. By all means the "Lusitania" should have been led on a secure northern route around Ireland to reach Liverpool. Honi soit qui mal y pense, but England needed the then still neutral USA for support and was eager to provoke any event to further discriminate Germany, and turn the US public tide against Germany.
The german embassy had even printed an article in the US newspapers warning passengers to use this very ship, because it might be sunk.
But despite all this propaganda from all sides the actual sinking was an accident, a mistake. The skipper of U20 mistook the Lusitania for another ship.
Even if the "Lusitania" was officially an auxiliary cruiser from its papers (which was merely a "trick" to get financial support from the Navy when the ship was built), it most probably would not have been sunk without its camouflage and sporting a clear visible flag. Despite all this propaganda and warnings U20 would not have sunk an obvious passenger ship. U-boats were forbidden to sink passenger ships even during this "unrestricted" U-boat war, which only took place for a short time. This was not made public because
1st it would have been difficult to explain to the german civilian population suffering from the blockade, and
2nd because Germany wanted England to believe civilian passenger ships would not be spared, because the abuse of neutral or no flag at all was common practice on english ships helping the Entente. But the official order not to attack passenger ships was indeed in effect for the time of the war.
The sinking of two passenger ships was, by all terror and death that it caused, a mistake - but a mistake of which England was not without guilt. When freighters and civilian ships (!) were being armed with guns it was impossible for german U-boats to follow the prize regulation, to stop ships, search them, control the papers and act accordingly - so some ships had to be judged through the periscope before doing so. But then there were enough incidents in which british or "neutral" ships suddenly fired at U-boats, which would go down after one or two hits (e.g. the "Nicosian" incident, but there were numerous others). This gave way to unintended sinkings, and international problems.
Trying to make the prize regulation impossible was an intended measure to provoke international scandals, and for propaganda purposes. You may call this cynical, and i agree.
" ... I must dissent, as I did in the earlier thread, regarding the
British naval blockade as a war crime. ..."
You state that blockades were common practice, but in no time of history did a blockade do what this one was intended to, and did - trying to starve out civilian population and brake their will by all means. Asquith and others had said exactly this before the war.
Germany had 750.000 civilian casualties due to lack of food alone in the winter of 1915. The sea trade had been strangled completely, and Germany was as dependant from overseas trade as was England, and other nations. This certainly sheds some light on the german intelligence concerning the reaction of other nations, and the Kaiser's belief in the Royal Family in England.
From different sources:
" ... The Allies had the advantages of greater resources of finance and raw materials. Britain maintained its naval dominance and could draw on its empire for support. In addition, because Germany was effectively blockaded, the United States, even though officially neutral for most of the war, served as a major source of supplies for the Allies. ..."
This is especially true for President Wilson who first wanted to join Germany - if i were cynical i would say after realizing that the growing war trade markets of France and England would come up for the missing trade with Germany, his humanitarism and concern for the free trade of the seas suddenly seemed to lack some of its quality.
Blockade, international public law and treaties:
" ... Soon after the outbreak of hostilities, Britain initiated a naval blockade of Germany. The strategy proved effective, cutting off vital military and civilian supplies,
although this blockade violated generally accepted international law codified by several international agreements of the past two centuries.[40] Britain mined international waters to prevent any ships from entering entire sections of ocean, causing danger to even neutral ships.[41]
Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare. ..."
This assumption would then prove wrong.
" ... All this indicates, simply, that no combatant nation's hands were
completely clean. The same can be said for every other war. ..."
I agree completely ! And Sherman's words are still true, for all kinds of war.
Thanks and greetings,
