I want to know the answer to the following question:
What month was a delay caused by Japanese rearguards north of Rangoon?
All the background I'm provided with is that "During April, Fourteenth Army advanced 300 miles (480 km) south towards Rangoon, the capital and principal port of Burma, but was delayed by Japanese rearguards 40 miles (64 km) north of Rangoon at the end of the month.". Is that enough to answer the question?
Answer: yes
