On June 8, 1191, King Richard I of England arrived at Acre in modern day Israel to join the Siege of Acre during the Third Crusade. From the article:
"Arriving with a Genoese fleet on April 20, Philip began constructing siege engines for assaulting Acre's walls. He was joined on June 8 by Richard who landed with 8,000 men. Richard initially sought a meeting with Saladin, though this was cancelled when the English leader fell ill. Effectively taking control of the siege, Richard pounded away at Acre's walls, but attempts to exploit the damage were thwarted by diversionary attacks by Saladin. These allowed the city's defenders to make needed repairs while the Crusaders were otherwise occupied.
On July 3, a major breach was created in Acre's walls, but the subsequent assault was repulsed. Seeing little alternative, the garrison offered to surrender on July 4. This offer was refused by Richard who rejected the terms offered by the garrison. Additional efforts on Saladin's part to relieve the city failed and following a major battle on July 11, the garrison again offered to surrender. This was accepted and the Crusaders entered the city. In victory, Conrad had the banners of Jerusalem, England, France, and Austria raised over the city."
