 Hegener argued de Jong and van Daalen's guerrilla actions had been quite effective due to Minahasa's natural suitability and the Japanese's lack of experience in dealing with guerrilla warfare.The group had initial hit-and-run successes, but as the local population's support for the Japanese grew and more troops were being allocated to fight them, the effectiveness of the guerrilla war eventually dwindled away.After the war, de Jong was made Knight Commander of the Militaire Williams-Orde, 4th Class and van Daalen received the Bronze Lion, both posthumously.
