The way interdiction manifested itself was by either pinpoint attacks through @royalnavy@birdsite.james.moody.name surface forces and submarines, or by the #fleetarm and the #RAF from the air, or by battles lasting several days with multiple attacks, as happened in mid-September 1941. F/O Greenhill on this mission would day exactly a month on during an attack on an #italiannavy convoy. @histodons #histodons
