...here what I find a very interesting (if not outright 'ultimately important') feature on coming-into-being of one of most important legends about the ongoing Yemen War:

How False Stories of Iran Arming the Houthis Were Used to Justify War in Yemen
Diplomatic cables released by WikiLeaks reveal that the story of the arms onboard the ship had been concocted by the government.

...
The government of the Republic of Yemen, then dominated by President Ali Abdullah Saleh, claimed that it had seized a vessel named Mahan 1 in Yemeni territorial waters on October 25, 2009, with a crew of five Iranians, and that it had found weapons onboard the ship. The UN expert panel report repeated the official story that authorities had confiscated the weapons and that the First Instance Court of Sana'a had convicted the crew of the Mahan 1 of smuggling arms from Iran to Yemen.

But diplomatic cables from the US Embassy in Yemen released by WikiLeaks in 2010 reveal that, although the ship and crew were indeed Iranian, the story of the arms onboard the ship had been concocted by the government. On October 27, 2009, the US Embassy sent a cable to the State Department noting that the Embassy of Yemen in Washington had issued a press statement announcing the seizure of a "foreign vessel carrying a quantity of arms and other goods...." But another cable dated November 11, 2009, reported that the government had "failed to substantiate its extravagant public claims that an Iranian ship seized off its coast on October 25 was carrying military trainers, weapons and explosives destined for the Houthis."
...

A follow-up Embassy cable five days later reported that the government had already begun to revise its story in light of the US knowledge that no arms had been found on board. "The ship was apparently empty when it was seized," according to the cable. "However, echoing a claim by Yemen Ambassador al-Hajj, FM [Foreign Minister] Qaairbi told Pol Chief [chief of the US Embassy's political section] on 11/15 the fact that the ship was empty indicated the arms had already been delivered."
...

Unlike the government's story of the Mahan 1 and its phantom weapons, the official claim that a ship called the Jihan 1, seized on January 23, 2013, had arms onboard was true. But the totality of the evidence shows that the story of an Iranian arms shipment to the Houthis was false.

The ship was stopped in Yemeni waters by a joint patrol of the Yemeni Coast Guard and the US Navy, and an inspection found a cache of weapons and ammunition. The cargo including man-portable surface-to-air missiles, 122-millimeter rockets, rocket-propelled grenade launchers, C-4 plastic explosive blocks and equipment for improvised explosive devices.

Some weeks later, the UN expert panel inspected the weaponry said to have been found on board the Jihan 1 and found labels stuck on ammunition boxes with the legend "Ministry of Sepah" - the former name of the Iranian military logistics ministry. The panel report said the panel had determined that "all available information placed the Islamic Republic of Iran at the centre of the Jihan operation."

But except for those labels, which could have been affixed to the boxes after the government had taken possession of the arms, nothing about the ship or the weapons actually pointed to Iran. All of the crew and the businessmen said to have arranged the shipment were Yemenis, according to the report. And the expert panel cited no evidence that the ship was Iranian or that the weapons were manufactured in Iran.
