Roman Invasion of Britain Map
I don't believe that Julius Caesar reported the soil was good....But according to the website below it goes like this......'Although Julius Caesar had visited Britain in 55BC (Before the birth of Christ) and reported that the soil was good, there was plenty of food and people that could be used as slaves, the Romans did not have a large enough army to invade and conquer Britain. It was AD (Anno Domini [after the birth of Christ]) or CE (Christian Era) 43 before the Romans, under the Emperor Claudius, were ready to conquer Britain.' and what happened in Britain is as shown on the map.
