<entity_0>, also known as the First Battle of the Odon, was a British offensive in the Second World War between <entity_1> and <entity_2>, during the Battle of <entity_3>. Preceded by Operation Martlet to secure the right flank of the advance, <entity_0> began early on <entity_1>, with units of the 15th (Scottish) Infantry Division advancing behind a rolling artillery barrage. Interpretations of the intention and conduct of <entity_0> differ but there is general agreement concerning its effect on the balance of forces in <entity_3>. The <entity_3> city of <entity_4> was a D-Day objective for the British 3rd Infantry Division that landed on Sword Beach on 6 <entity_2>. Poor weather hampered the start of <entity_0> on <entity_1>, where rain over the battlefield had made the ground boggy; over the United Kingdom in the early hours, there was a heavy mist resulting in aircraft being grounded and the bombing being called off. This was partially endorsed by Hausser, who on <entity_2> proposed a retirement from <entity_4>.
