At dawn on Sunday, 25 June 1950, the Korean People's Army crossed the 38th parallel behind artillery fire. The KPA justified its assault with the claim that ROK troops had attacked first, and that they were aiming to arrest and execute the "bandit traitor Syngman Rhee". Fighting began on the strategic Ongjin peninsula in the west. There were initial South Korean claims that they had captured the city of Haeju, and this sequence of events has led some scholars to argue that the South Koreans actually fired first.
Who was the Korean People's Army trying to execute?
Syngman Rhee

During the English Civil War the majority of Londoners supported the Parliamentary cause. After an initial advance by the Royalists in 1642 culminating in the battles of Brentford and Turnham Green, London was surrounded by defensive perimeter wall known as the Lines of Communication. The lines were built by an up to 20,000 people, and were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.
How long did it take to build the Lines of Communication?
under two months

Chopin's tombstone, featuring the muse of music, Euterpe, weeping over a broken lyre, was designed and sculpted by Clésinger. The expenses of the funeral and monument, amounting to 5,000 francs, were covered by Jane Stirling, who also paid for the return of the composer's sister Ludwika to Warsaw. Ludwika took Chopin's heart in an urn, preserved in alcohol, back to Poland in 1850.[n 9] She also took a collection of two hundred letters from Sand to Chopin; after 1851 these were returned to Sand, who seems to have destroyed them.
