Khalid is greatest general of all time arguably  Alexander is the second greatest general For example compare battle of Nihawand to Guagamela Archaemenids recovered Sassanids never recovered In Yarmouk Khalid outnumbered  to  but still victorious He did not inherit an army like Alexanders macedonian army from King Philip He vanquished Persia and devastated Byzantium in  years Plus he was many times outnumbered None of these factors apply to Napoleon or Hannibal or Alexander Acknowledge facts and logical truth Dont become biased because Khalid was a muslim Recognise his military genius and supremacy as the greatest general Just as you recognise Shakespeare as arguably best writer in English langauge and Beethoven as arguably best composer Acknowledge this truth impartially and accept my edit Khalid was arguably the greatest military commander in history    PS stop referring to me as a vandaliser I am speaking the stark truth I respect wikipedia and want to mantain its status as the most comprehensive voluminous and reputable informational resource on the internet   Cordially    Don Zaloog
